Hormone Levels In The First Trimester Of Your Pregnancy

The most drastic hormonal changes will occur in your first trimester. Youll witness a substantial increase in the production of progesterone and estrogen.

Progesterone is responsible for the thickening of your uterine lining so that an egg can implant. It also acts as a relaxant to prevent your uterus from contracting until your due date. For some women, increased progesterone levels are linked to the mood swings they experience in their first trimester.

Estrogen causes an increase in blood flow to the placenta. The placenta is a temporary organ created to connect the fetus to the uterine wall, allowing the uptake of nutrients, the elimination of waste, and other functions that are vital for embryo development . This increase in estrogen can lead to frequent urination and make your breasts feel tender. On the plus side, the increased levels of estrogen have also been attributed to being responsible for what is known as the healthy pregnancy glow .

hCG starts being produced in the first trimester. It plays a crucial part in establishing and maintaining pregnancy, through placentation – a technical word used to describe the formation of the placenta. In the first 10 weeks of pregnancy, your hCG levels double every two days . This rise is responsible for stopping your period and preparing the placenta for a baby. On the downside, rising levels of hCG often cause nausea and vomiting, what many women recognize as morning sickness.

What Is Human Chorionic Gonadotrophin

Human chorionic gonadotrophin is a hormone produced by the placenta during pregnancy. Its sometimes called the pregnancy hormone because of its unique role in supporting a pregnancy. HCG is found in your urine or blood around 10 to 11 days after conception . Your hCG levels are the highest towards the end of the first trimester , then decline for the rest of your pregnancy. Healthcare providers measure hCG to confirm a pregnancy and provide details on how the pregnancy is progressing.

Ways Men’s Hormones Change During Pregnancy Too

A lot of studies on pregnancy and parenthood are divided on gender lines. What happens to the body is restricted to women during the expectant months what happens afterwards is spread between both parents. It’s how we know, for instance, that the “happy chemical” oxytocin spikes in men once they become dads, or even when they play with young infants. But, increasingly, people are discovering that men have physical responses to pregnancy in their partners as well, and that these changes often happen on a hormonal level. If you’re a man and your partner’s pregnant, chances are you’re also going to experience some interesting changes in your hormonal make-up, though as yet we’re not entirely clear what some of them are, or why.

The phenomenon of couvade syndrome, or sympathetic pregnancy, has garnered a lot of scientific jeering over the years, but it does seem as if the male body does make some serious changes when it’s partnered with a pregnant lady. It’s well-known that dads often gain “sympathetic” weight during a partner’s pregnancy, a phenomenon that’s now thought to be an adaptive process to cope with the extra energy they’ll need after the child’s born. But there’s scholarly argument as to what actually happens to men’s hormones during a partner’s pregnancy, because some studies show select hormones changing, and others don’t. For some of these ideas, the jury’s still out.

What Does Relaxin Hormone Do

hormones of labor

Your ovaries make relaxin before you become pregnant. It rises in the second half of your menstrual cycle. It also prepares the lining of your uterus so that if fertilization occurs, implantation is more successful. The relaxing properties of relaxin also help prevent uterine contractions during pregnancy.

Relaxin levels continue to rise if youre pregnant. This is because the placenta will also begin producing relaxin. The placenta is an organ that provides food, nutrients and oxygen to the fetus during pregnancy. Relaxin levels peak at around 12 to 14 weeks of pregnancy.

As the fetus grows in your uterus, relaxin helps your body stretch. Its helpful during childbirth when your pelvis needs to relax to allow your baby to descend the birth canal. Relaxin also helps to prepare your cervix for labor and delivery.

What are the functions of relaxin during pregnancy?

Relaxin plays a unique role in relaxing your muscles, ligaments and joints during pregnancy. Some of the functions of relaxin during pregnancy include:

Your Hormones In The Second Trimester

The second trimester is commonly known as the best trimester because at around week 13, many women start to feel human again. Nausea often starts to dissipate, but youll start to notice other changes.

For one thing, your muscles and joints may feel strange, or uncomfortable, especially around your pelvis. This is thanks to relaxin, a hormone that helps relax the smooth muscles in the pelvis, such as the cervix and uterus, and promote the growth of the placenta. While this might make prenatal yoga a bit easier, unfortunately, it can also cause women to experience some aches and pains in their ligaments, or even experience injuries more easily.

Schwartzexperienced serious back pain and soreness in her right hip and pelvis during her second trimester, likely thanks to this hormone. I could barely walk, she says. I would drive home from work and I couldnt get out of the driver’s seat for half an hour. The pain didnt dissipate until she gave birth.

Cortisol also increases during pregnancy, but despite what you hear about this stress hormone, its not all badits important for the developing fetus because it can help regulate your metabolism and control blood sugar levels. High levels of cortisol may bealso associated with some of those unfortunate symptoms like stretch marks, blood pressure issues, and added redness in the face and cheeks, says Babicki-Farrugia.

Side Effects Of Relaxin Hormone During Pregnancy

The same qualities of the relaxin hormone that helps with pregnancy, delivery and lactation have a flip side too. Some of the side effects of relaxin hormone during pregnancy are:

  • Back pain: The relaxing property of the hormone relaxin affects the ligaments of the spine. During pregnancy, just like other ligaments in the body, the ligament of spine also becomes more elastic and less stable. This makes the expecting mother more susceptible to the back pain
  • Pelvic Girdle Pain: The relaxin hormone often tampers with the pelvic girdle structure which is made up of lot of joints of legs, hips etc. As a result, all the ligaments in the joints become more elastic and loose stability. This can often cause pelvic girdle pain during pregnancy
  • Increased risk of injury: During pregnancy, especially during the last trimester, the overly stretched muscle increases the chance of injury in the pregnant women as they become more wobbly and unsteady due to the increased levels of relaxin hormone

Although relaxin hormone has its side effects, but this hormone is important to make the birth process easier. So, the pregnant women should take extra care of their posture during pregnancy, especially during the first and the third trimesters, when relaxin hormone is at its peak in the body.

Understanding The Oesophagus And Stomach

When we eat, food passes down the gullet into the stomach. Cells in the lining of the stomach make acid and other chemicals which help to digest food.

Stomach cells also make mucus which protects them from damage caused by the acid. The cells lining the oesophagus are different and have little protection from acid.

There is a circular band of muscle at the junction between the oesophagus and stomach. This relaxes to allow food down but normally tightens up and stops food and acid leaking back up into the oesophagus. In effect, the sphincter acts like a valve.

What Role Does Hcg Play In Pregnancy

Physiological Changes During Pregnancy

This hormone amps up the production of estrogen and progesterone, though you and hCG may have already met if youve taken a home pregnancy test. Yup, its this chemical that coaxes a sweet happy face to appear on the pee stick.

Early on in pregnancy, hCG levels are low, but they soon rise and double every two days, peaking between weeks 7 and 12 and then falling back at the start of your second trimester. Next, the placenta starts making estrogen and progesterone, though hCG is still with you. In fact, this hormone affects the immune system, sometimes leaving you more vulnerable to colds and the flu.

Avoiding Indigestion And Heartburn

If your symptoms are mild, its possible that changes to your diet or lifestyle may help prevent indigestion and heartburn. You could try:

  • eating smaller meals, more often
  • avoiding eating just before bed
  • avoiding foods and drinks that you suspect give you heartburn
  • raise the head of your bed by 10 to 15cm
  • sleep on your left side

If your indigestion is not helped by diet and lifestyle changes, or your symptoms are more severe, your doctor or midwife may suggest that you take a medicine for indigestion that is safe to use during pregnancy. Medicines can neutralise the acid in your stomach, reduce the amount of acid produced by your stomach and stop the acid rising into your oesophagus.

What Does Relaxin Feel Like

You cant feel relaxin, and it doesnt usually cause pain. Some people believe its relaxing effect causes gastrointestinal issues because it prevents your intestines from tightening as they usually do. This can cause constipation, bloating or indigestion in some pregnant people.

Relaxin can also weaken your pelvic floor, which may have an effect on bladder control. It can also negatively affect your posture because your back and pelvis are looser.

Relaxin makes you more flexible during pregnancy, which is great for the growing fetus and for delivery. Unfortunately, this can make you more susceptible to injuries and sprains. Take extra care during pregnancy since you are a little more unsteady on your feet. Its a good idea to stick to gentle exercises and avoid heavy lifting.

After the first few months is when most women begin to experience a high libido during pregnancy, says Gleaton. The second trimester usually brings more energy, less nausea, and an increased desire to do most activities, including sex, she says. And for many women that libido increases as pregnancy continues, according to Abdur-Rahman.

Some . They may notice an increased libido before they even realize theyre pregnant, Abdur-Rahman says. This has to do with the hCg hormone and extra blood flow to the clitoris and genital area in general. The hCg hormone is produced by the placenta and it helps thicken your uterine lining.

Many women fall into one of two camps when it comes to the hCg hormone they want to get it on all the time, or they become intimately familiar with the toilet bowl. If you are in the former camp, and especially if you are feeling frisky during the last two trimesters of your pregnancy, you are probably trying to figure out the most comfortable pregnancy sex positions to accommodate your growing bump and to really take advantage of that extra blood flow down there.
