Progesterone LevelsPregnancy would not be possible without progesterone!
Progesterone is a hormone that the ovary produces during pregnancy. The placenta will maintain progesterone levels throughout the pregnancy. Progesterone is important and plays a crucial role in conception and the development of a fetus. Without progesterone, pregnancy would be impossible.
During pregnancy, progesterone serves many purposes. Progesterone allows the endometrium to develop, remain thick and secrete fluids. The placenta functions and fights off unwanted cells near the uterus because of progesterone. Progesterone stimulates the growth of breat tissue and encourages lactation after birth. The hormone is responsible for strengthening the mucus plug, which covers the cervix to fight infection. Progesterone also keeps the uterus from contracting to ensure that the baby stays in the uterus for optimal growth. However as your pregnancy comes to an end, progesterone levels will drop and this will stimulate contractions of the uterus. The contractions will then lead to the birth of your baby!
Normal progesterone levels during a woman's menstrual cycle and during pregnancy are different. From day 1-14 of a menstrual cycle, the levels should be 1 to 1.5 ng/ml. From day 15 to 28, the levels vary from 2-28 ng/ml. During the first trimester of pregnancy, normal levels can range from 9-47 ng/ml. Second trimester levels will range from 17-147 ng/ml and third trimester levels should be between 55 and 200 ng/ml.
Low progesterone levels can be detected with a blood test. In the early weeks of pregnancy, low levels may indicate a threatened miscarriage. Because adequate levels of progesterone are needed to carry a pregnancy to term, it is important that doctors check a woman's level of progesterone if a problem is suspected.
If progesterone levels are too high during pregnancy, a woman may experience constipation, heartburn, a runny nose, blurry eyes and an increased chance of kidney infections.

I am on the progesterone suppositories and have been on them since week 5 and i am almost 10 weeks along now. i don't know what my levels were at the first time i had blood taken but i am going to make sure and ask when i go in for my appointment next week. so far it just seems to me like it has increased the symptoms of being pregnant. i had a m/c last june at 8 weeks, so i like to think that this one will work out cause yeah its only one week but still have symptoms and its lasted longer than the other. hopingmarch

I wanted to respond to your question/concern marchbabies. I am 4 1/2 weeks pregnant and had a previous miscarriage in May. My progesterone level were taken about a week ago and it was 25.7 and yesterday I had a blood test and they were 20.4. Of course I am really nervous about that but my midwife tells me it is okay for progesterone to fluctuate as long as it doesn't drop really low, like under 10. I am still worried and I probably will be until at least 12 weeks. I just wanted you to know I had the same experience. ichinisan

I am 6 weeks pregnant after 3 m/c. Last week, my progesterone levels were 19.8 and this week they dropped to 17.9. Anyone had this happen? Is the drop a bad sign? Do you think progesterone supplements would be necessary? I haven't had any spotting yet and just a little light cramping but I am worried sick to lose this pregnancy for the 4th time in row. Any success stories?? adriana03

I was on progesterone suppositories for the first trimester and didn't have any problems. I'm 25 weeks now and my baby is healthy and growing right on schedule! It's very common to be used when there is a threat or risk of miscarriage. Good luck with your pregnancy! PreggersMissy

I recently went to the doctor a week ago and had my progesterone levels tested to see if I was ovulating. They called me the next day and told me that I did not ovulate - level was 6.3. I got real upset and thought that I was going to need fertility drugs in order to conceive. Well, after drinking beer over the weekend, I found out I was about 5 weeks pregnant. (I didn't know that you don't ovulate when pregnant) My doctor immediately became worried after realizing that my progesterone levels were so low so he tested it again and it was only 6.6 and he then prescribed progesterone vaginal suppositories. I was wondering if anyone has experienced severe side effects or believes that progesterone causes problems with the baby..... CelticBabe2009

I was diagnosed with low progesterone (7) too after a 5 months of trying, a miscarriage, and another 8 months of trying. They prescribed Clomid to be taken on my next cycle. Before I was able to take it, I read that a diet high in raw fruits and veggies will raise it naturally, so I tried it for a bit over three weeks (days 7-30). BFP on day 30 without any drugs! My doc immediately put me on prog. supplements for the first trimester (I am about to enter week 11). I won't say that it will work for everyone, but the worst that will happen is you will be eating healthier...... flutterflybaby1999

I wonder why my doctor never gave me a choice to check into my progest levels? even when i asked if i could get checked. i had a mc at 5weeks in aug 08 and i thought maybe since i had irregular periods maybe thats why i didnt have enought progest. soon2bemamaof4

Hi girls! I just found out yesterday that I am pregnant again! I am hoping and praying this time it will turn out okay. During my last pregnancy, at about 4 and a half weeks, my Dr. called me to inform me that my progesterone level was at 5....and she usually likes to see it around 16 at that point. She gave me a prescription for Prometrium to try and up my levels. Right after I started taking it, I miscarried. It could be that it was just meant to happen, but I can't help but worry that maybe the Prometrium triggered it. She told me if I got pregnant again, to go ahead and start taking it right away (she said it wouldn't hurt if my levels were normal)....but I'm so scared! I haven't been to the Dr. yet to even know what my levels are and I'm supposed to start taking this again. Can anyone offer any advice? PLEASE? AandDsMommy

I am on the shots once a week also and I just want to know how long after you stop taking the shots does it take for labor to start??? I'm very anxious to get him out and I am miserable. I am only 30 weeks by the way and yes I realize he is not coming all that soon, I stop my shot between 34 and 36 weeks. I just wanna know how long it took for you guys to go into labor after using this shot?!?!?! LMDYNOMITE
