Progesterone Tablets During Pregnancy
You may be wondering why your doctor is having you take progesterone tablets in pregnancy. Having stable progesterone levels is an important part of the reproductive cycle from your periods being regular to building up your uterus for possible pregnancy.
Your ovaries are in charge of producing, releasing, and keeping progesterone levels where they need to be. In the first weeks of pregnancy, the ovaries produce needed progesterone until the placenta begins to produce it on its own in the second trimester. Sometimes, this doesn't always work right. This article will explain the reasons for needing extra progesterone, how it works, and any safety concerns.

Side-Effects of Progesterone Tablets
The side-effects of progesterone are pretty much the same as normal pregnancy symptoms; however they may be a little more intense depending on how much progesterone you are taking. The side-effects are as follows:
1. Headaches
The headaches you get in pregnancy are caused by increased progesterone levels. Part of this is due to more relaxed blood vessels to help improve your blood flow. The blood vessels leading to your head and brain also relax and the increased blood flow to your head causes almost intolerable headaches at times. Migraine sufferers may notice more migraines while taking progesterone.
2. Constipation
This isn’t a very comfortable side-effect, but it does have a good reason. Progesterone slows down your intestines by relaxing the muscle walls. This prevents strong bowel contractions from triggering contractions in your uterus. The benefit to you and your baby is the food stays in longer so your body can extract every bit of nutrition from the food that you eat.
3. Fatigue
This inevitable sign in early pregnancy can be heightened if you take progesterone tablets during pregnancy. Progesterone naturally relaxes your central nervous system and can make you feel sleepy. The good news is, if you suffer from anxiety or are tense you may feel much more relaxed.
4. Sore Breasts
You can thank progesterone for breast soreness in early pregnancy. Taking progesterone tablets may cause increased breast soreness. Find a good sports bra because your nipples may be very tender too.
5. Moodiness
It is pretty normal to have mood swings early in pregnancy. When you take progesterone tablets during pregnancy, these may be a bit more intense than they normally would. You may experience increased Depression, bouts of anger, and even intense happiness at times.
6. Stuffed Up Nose
Your nose has smooth muscles that help move Mucus through and out of your body. When you take progesterone, these muscles relax and have a harder time doing their job. This can lead to an increase in nose stuffiness.
7. Other Uncommon Side Effects

Are There Any Risks or Precautions to Take?
While the FDA (Food and Drug Administration) has neither approved or disapproved the use of progesterone tablets during pregnancy, it has been found safe for use. There were no adverse effects reported on mother or fetus when studied in animals. Since being used in women, there have been no reports of adverse effects to mother and baby. Your doctor will decide if the benefits are more than the risk when prescribing you this medication.
There was only one birth defect reported during progesterone use in pregnancy. This baby was born with a cleft palate, which can happen in any situation even without progesterone. Very rarely, there have been pregnancy losses in women using progesterone and the cause was never pinpointed. Make sure you are only using progesterone as directed by your doctor.
