Are you pregnant or planning to conceive? Do you want to keep a track of your health through these crucial months? Are you aware of the hormonal fluctuations your body goes through and how it can affect your pregnancy?

If you have heard about progesterone, you may be aware that it has quite an important role to play during your pregnancy. Read our post here and learn more about this essential hormone progesterone in early pregnancy and understand how you can keep track of its levels and uses during pregnancy.

What Is Progesterone?

Progesterone is one of the most important hormones that play a major role in your body while you are pregnant. It is called the pregnancy hormone for this very reason. Progesterone is a female hormone. When you ovulate, your ovaries release a mature egg. At the same time, your ovaries also produce progesterone (1).

What Is The Use Of Progesterone Level During Pregnancy?

The hormone progesterone helps to prepare the lining of your uterus, also k

nown as the endometrium. It prepares your uterus to receive the egg when it fertilizes after coming in contact with the sperm. If the egg does fertilize, you experience a drop in the progesterone levels and your monthly periods begin (2).

What Should Be The Levels Of Progesterone During Pregnancy?

What are normal progesterone levels during pregnancy? When you are pregnant, the level of progesterone in your body will be ten times that of a woman who is not pregnant. Here are a few quick facts you should keep in mind before you start calculating or checking your progesterone levels:

  • Your progesterone levels usually change from one day to the other and as fast as one hour to the next.
  • Sometimes, the same progesterone test done at one laboratory may give different results than the one you did around the same time at another laboratory.
  • Once you have your food, your progesterone levels can drop down as low as 50 percent to what it was before you had your meal. Hence, you should always have your blood tests done in the morning before eating anything.
  • When you are pregnant, your progesterone levels should at least be within a range of 10 to 12 ng per ml. It will ensure your pregnancy progresses well. An ideal level of the hormone progesterone, while you are pregnant, should be between 16 to 18 ng per ml.
  • If you have an ectopic pregnancy, you will have a much lower level of progesterone as compared to a woman who has an intrauterine pregnancy (3).

As yet, there is no specific level of the hormone progesterone that is normal while you are ovulating or are pregnant. The level of progesterone you should have while you are pregnant depends on the gestational age of your pregnancy. Gestational age occurs from the first day you had your last monthly period.

However, you can track the steps below to have a general idea of what your progesterone levels should be like while you are pregnant (4):

1. Gestational Week 1 To 2:

  • During the first and second week of your gestation, you are not yet technically pregnant.
  • It is the time when your body is preparing itself for the big day.
  • At this stage, your ovaries will produce a very small amount of the hormone progesterone. The levels can be as small as 0.1 ng per ml to 1.5 ng per ml.
  • The end of your second gestational week is when you will most likely release an egg that will fertilize.

2. Gestational Week 3 To 4:

  • Once you experience ovulation, a part of your ovaries will start the production of progesterone.
  • The levels of progesterone in your body will start increasing to a level above 2 ng per ml.
  • During the first part of gestational week three, your progesterone levels will start increasing by about one to three ng per ml for every one to two days. The progress will continue until your progesterone reaches a level of 10 to 29 ng per ml.

3. Gestational Week 5 To 6:

  • By the time you reach gestational week six, your progesterone levels will reach somewhere between 10 to 29 ng per ml.
  • By now, your doctor will check if your progesterone levels can reach up to 6 to 10 ng per ml, which is an indication that your pregnancy is going well.
  • At this stage, the progesterone level in pregnancy will help to stimulate the growth of blood vessels in your uterus. It will help to keep your placenta healthy and to function well so that it can provide nourishment to your unborn baby.
  • It is also the time when your body will experience what is commonly known as the pregnancy glow. It happens when the blood vessels will start to grow on all parts of your body. Sometimes, however, you may experience some redness, itching or rashes as a result of the same.

4. Gestational Week 7 To 14:

  • Between gestation weeks 7 and 14, your placenta will start producing more progesterone.
  • The level of your progesterone may stay stable, or sometimes even start reducing.
  • Once you hit the tenth week of gestation, the levels of your progesterone will start increasing again. The levels can sometimes go as high as what it was during your first trimester, between 15 and 60 ng per ml.
  • After the stage, the levels of progesterone in your body will keep increasing.
  • In case you are carrying multiple babies, like twins or triplets, your progesterone levels will be higher.
  • As your progesterone levels increase, it will help to relax and smooth the muscles in your uterus. It will help to make more room for your baby as the weeks pass and will also help to prevent any uterine contractions.
  • As a side effect, you could also experience heartburn, constipation, hemorrhoids or indigestion.
