How Do Hormonal Birth Control Methods Work

I Forgot To Take My Pill What Do I Do

How Does Hormonal Birth Control *Actually* Work?

Women taking combination birth control pills should take the missed pill as soon as they remember and then take the next pill as they normally would. In some cases, this means taking two pills on the same day. Although the risk of pregnancy is minimal, it is still a good idea to use a back-up method of birth control, such as condom, for the next seven days. If the forgotten pill occurred during day 15 to 21 of your pill cycle, then check with your doctor for special instructions. In some cases, you may be advised to skip the pill-free/ sugar pill week and just start a new package as soon as you finish your current set of hormonal pills.

Women using progestin only oral contraceptives should take the forgotten pill as soon as they remember and then take the next pill as they normally would. In some cases, this may mean that you take two pills on the same day. You will need to use a back-up method of birth control for the next two days.

Weighing The Pros And Cons

All forms of hormonal contraception are similarly effective at preventing pregnancy. A womans choice of contraception may depend on how well she tolerates the different kinds, and how she feels about the potential side effects. Another factor is what the contraceptive method involves: Does she mind swallowing a pill every day? Would wearing a patch on her body for several weeks bother her? Can she feel the vaginal ring inside her during sex? Women have to find out for themselves what is most important to them and which method they tolerate the best.

As well as hormonal contraceptives, there are also non-hormonal contraceptives. You can get more information about the different kinds of contraceptives from your doctor or womens health center.

Find Balance Between Efficacy And Side Effects

The side effects of hormonal birth control vary by method, but across all types, changes in bleeding can occur, as can headache, breast tenderness, and nausea. Usually, systemic contraceptives like the Pill and the patch tend to cause more side effects than similar combination methods that work locally, like the ring, Dr. Creinin says. The hormonal IUD delivers only progestin locally to the uterus, so the amount that travels throughout the body is very small, reducing the risk of side effects, he adds. Some women find other IUD side effects, like cramping and irregular bleeding, to be intolerable.

  • Are breastfeeding.
  • Have any serious health problems, such as heart disease, high blood pressure, migraine headaches, or diabetes.
  • Have had blood clots in the legs or lungs , or have a close family member who had blood clots in the legs or lungs.

When Do I Start Another Birth Control Pill Pack

Youâll start each new birth control pill pack on the same day of the week that you initially started it. If you are on the 21-day pill pack, start the new pill pack 7 days after you finished the old pill pack. If you are on the 28-day pill pack, begin the new pack after taking the last pill in the old pack.

Start your new pill pack on schedule, whether or not you get your period or are still having your period.

What About Side Effects

  • The most common side effect is irritation of the vulva and vaginal area, such as a burning or an itching sensation. Nearly a third of women reported one of these symptoms.
  • Less than 1% of women had more serious side effects, such as severe urinary tract infection.
  • Nearly 10% of male partners reported some itching, burning, or pain as well after their partner used Phexxi.

Phexxi cannot prevent sexually transmitted infections , so women should continue to use condoms to prevent STIs.

Which Types Of Birth Control Help Prevent Sexually Transmitted Infections

How Does Hormonal Birth Control Work and Affect the Body

Only two types can protect you from STIs, including HIV: male condoms and female condoms.

While condoms are the best way to prevent STIs if you have sex, they are not the most effective type of birth control. If you have sex, the best way to prevent both STIs and pregnancy is to use what is called “dual protection.” Dual protection means you use a condom to prevent STIs each time you have sex, and at the same time, you use a more effective form of birth control, such as an IUD, implant, or shot.

Does Breastfeeding Prevent Pregnancy

Breastfeeding can be a short-term method of birth control in very specific situations. The risk of pregnancy is less than 2 in 100 if all three of these describe you:

  • You have a baby who is less than 6 months old
  • You exclusively breastfeed, meaning that you only feed your baby your breastmilk all of the time
  • You have not gotten a period after childbirth

Talk to your doctor about birth control if you do not want to get pregnant while nursing.

Birth Control Implant Removal

Taking out the implant is quick and simple. Donât try to do it yourself. Your doctor needs to remove it. While youâre in the office theyâll:

  • Clean the area to prevent infection
  • Give you a shot with medicine to numb the site
  • Make a small cut at the top of the implant and remove it

It could take as long as 20 minutes if thereâs a lot of scar tissue in the area. If the doctor canât easily find the implant, they might take an X-ray to locate it.

Your arm might be sore after the implant comes out. Youâll need to:

  • Wear a bandage for 48 hours
  • Keep the area dry for 24 hours

How Much Effort Am I Willing To Put Into My Birth Control

Some birth control methods require more effort than others. Be honest about how much effort you are willing to put into birth control. Birth control must be used correctly in order to prevent pregnancy. If you are not comfortable with or might not consistently use a birth control method for any reason, that method is not likely to be reliable for you in the long run.

  • Long-acting reversible contraception , such as IUDs, works to prevent pregnancy for 3 to 10 years. Once it is in place you don’t need to do anything.
  • Hormone shots are needed every 3 months.
  • Barrier methods can interrupt sex and must be used every time you have sex. Diaphragms are not widely available in Canada. Buying the necessary spermicidal jelly to use with the diaphragm is difficult.
  • Combination pills are taken each day. Progestin-only pills must be taken at the same time each day. If you miss a pill you will need to use a backup birth control method.
  • Patches are replaced 3 times each month.
  • Vaginal rings are inserted into the vagina one time each month.
  • Fertility awareness requires that a couple chart the time during a woman’s menstrual cycle when she is most likely to become pregnant and avoid intercourse or use a barrier method during that time.
  • Sterilization is a surgical procedure done for men or women who decide that they do not want to have any children. Sterilization is intended to be permanent.

A Different Nonhormonal Birth Control Option


Until recently, people seeking hormone-free birth control have found few options available. The most effective and long-lasting nonhormonal option is the copper intrauterine device . Barrier methods sometimes are paired with spermicide to boost pregnancy prevention rates, or spermicides may be used alone . Apps and tests to track fertile days bring a high-tech sheen to the so-called rhythm method, but most ob/gyns do not recommend these as a way to prevent pregnancy.

Not until 2020 did the FDA approve a new nonhormonal birth control, Phexxi, which came on the market last fall. Should you try it if youre looking for a new option?

What Is The Difference Between Paragard And Mirena

The TCu380A is a copper-containing IUD. The IUD is a small T-shaped device with a monofilament tail that is inserted into the uterus by a health care practitioner in the office setting. When inserted into the uterus, the arms of the T are folded down, but they then open out to form the top of the T. The device rests inside the uterus with the base of the T just above the cervix and the arms of the T extending horizontally across the uterus. A short piece of monofilament string attached to the IUD extends through the cervix into the vagina. This string makes it possible to be sure that the IUD is still in the uterus.

It releases copper from a copper wire that is wrapped around the base. The released copper contributes to an inflammatory reaction in the uterus that helps prevent fertilization of the egg. It is approved to remain in place for up to 10 years.

Levonorgestrel-releasing IUD : This form of IUD releases a progestin hormone from the vertical part of the T. Progestin acts to thicken cervical mucus, creating a barrier to sperm, as well as renders the lining of the uterus inhospitable to implantation of a pregnancy. This form of IUD is approved for up to five years of use.

What Are The Hormonal Methods

  • Birth control pills are taken daily as prescribed by your healthcare provider.
  • Depo-Provera is an injection given by your health care provider that prevents pregnancy for three months.
  • NuvaRing, or vaginal ring, is a flexible ring that is inserted into the vagina for three weeks, removed for one week, and then replaced with a new ring. The ring releases estrogen and progesterone into your body.
  • The IUD Mirena is a small plastic device containing hormones and is inserted into the uterus for five years.

When To Call A Doctor

For many methods of birth control, you’ll need to see your doctor to get a prescription. If you want to start birth control, talk with your doctor about options that are right for you.

How Are Birth Control Pills Packaged

Hormonal Birth Control: How It Works

You get a set of pills packaged in a thin case. Pill packs containing regular birth control pills have either 21 or 28 pills. Twenty-one-day pill packs contain 21 active pills. Twenty-eight-day pill packs contain 21 active pills and seven inactive pills. The pill packs are marked with the days of the week to remind you to take a pill every day. The seven inactive pills in the 28-day pill pack are added so youâre reminded to start a new pill pack after 28 days.

Some newer pills have only two inactive pills or even none. It’s important to always take all the pills to be sure youâre protected from getting pregnant.

A package of extended-cycle Seasonale contains 84 active pink tablets and seven inactive white pills. With Seasonique and LoSeasonique, the last seven pills contain estrogen only.

Choosing Your Birth Control Method

Selecting which type of birth control to use can be very confusing. From birth control pills to birth control implants, there are many options to choose from. It helps to start by answering a few basic questions. Consider the following:

  • How important is it for you to be protected from STDs? Not all birth control methods protect against STDs.
  • How effective do you want your birth control? Some birth control methods are more effective than others.
  • Are convenience and cost important in your decision? Do you want birth control that lasts a while? How much can you afford to spend on birth control?
  • Does sexual pleasure affect your decision in selecting a birth control method? Do you want a birth control that enhances your sex life?

How Does It Work

Most birth control pills are “combination pills” containing a mix of the hormones estrogen;and progesterone;to prevent ovulation;. A woman cannot get pregnant if she doesn’t ovulate because there is no egg to be fertilized.

The Pill also works by thickening the mucus around the cervix, which makes it difficult for sperm to enter the uterus and reach any eggs that may have been released. The hormones in the Pill can also sometimes affect the lining of the uterus, making it difficult for an egg to attach to the wall of the uterus.

Can I Take The Pill While Breastfeeding

The combination birth control pill contains estrogen, which can decrease milk production. If you are breastfeeding, your healthcare provider may recommend taking the progestin-only pill instead. However, some women may use estrogen-containing pills once milk supply is fully established, and a womans risk of blood clots is minimized.

7 Hormonal Birth Control Methods & How They Work

Take your pill every day at the same time. This is especially important if youâre on the progestin-only minipill, which has a smaller margin for error than regular pills with both estrogen and progestin. It may help to set an alarm on your phone or post a calendar on your fridge as a reminder. When you finish a packet , take the first pill in a new packet the next day.

Some medications, including the antibiotic rifampin and the herb St. Johns wort, can interact with birth control pills. So use a back-up contraceptive.

What Are The Advantages And Disadvantages Of Hormonal Contraceptives

The biggest advantage of hormonal contraceptives is their reliability: Studies have shown that only about 1 out of 1,000 women get pregnant per cycle if they take the pill or use a contraceptive skin patch or vaginal ring properly.

Hormonal contraceptives can also relieve period pain, and often lead to lighter periods. If a teenage girl or woman has acne, the hormones may improve her skin too.

The potential disadvantages include side effects such as headaches, nausea, sore breasts and vaginal yeast infections . The hormones can also cause spotting between periods or lead to mood swings, and may reduce womens sexual desire.

And there is a small risk of blood clots forming . This risk is higher in women over the age of 40, as well as in women who smoke, are very overweight, or have a higher risk of vascular disease in their family.

Third- and fourth-generation birth control pills appear to increase the risk of thrombosis more than older first- and second-generation pills do . It is estimated that thrombosis occurs within one year in

  • about 9 to 12 out of 10,000 women who regularly take a birth control pill containing desogestrel, gestodene or drospirenone.
  • about 5 to 7 out of 10,000 women who regularly take a birth control pill containing levonorgestrel or norgestimate.

For comparison, thrombosis occurs in about 2 out of 10,000 women who arent on the pill.

How Do Hormones In Birth Control Work

The hormones in some methods of birth control are similar to the ones womens bodies makeclose enough that the body recognizes them as estrogen and progesterone. There are multiple kinds of hormonal birth control, each with unique ingredients that are released differently.

The IUD, the implant, the shot, and the mini-pill

The Mirena and Skyla;IUDs release a small amount of a progestin hormone called levonorgestrel. Levonorgestrel is one of the longest-studied types of progestin, and all the scientific evidence to date shows it is super safe. This chart shows the average amount of levonorgestrel measured in the blood of women who have used Mirena or Skyla for about a year. These are averages, and individual women may have higher or lower amountsthats what the ± means. The amount of levonorgestrel released by these IUDs stays very steady day to day, but declines slowly to even lower levels after the first year. Almost all of the levonorgestrel stays in the uterus; the chart below shows how little is in the blood stream.

How does this amount of levonorgestrel impact womens bodies? Most women using Skyla have their usual changes in estrogen and progesterone each cycle, and most release an egg each month. Many women using the Mirena are having their usual hormonal cycles after a year and still releasing an egg. The main way these IUDs work to prevent pregnancy is by keeping cervical mucus thick so sperm cant get through the cervix to meet with an egg.
