Progesterone Levels

Pregnancy would not be possible without progesterone!

Progesterone Levels

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.

CBONITA- I also had a very difficult pregnancy with my first. I had my son at 32 wks and was on bed rest at the hospital for 6 wks due to a ruptured membrane. I started taking progesterone shots with my second from 16 weeks and now I am 33 wks and happy to say still pregnant, moving around and not on bed rest. My progesterone dose ends at 35 wks but I'll be very happy if I even get to 35 wks and I'll be ok if I even give birth 36-37 wks. I know someone else who also had a difficult time with pregnancies and rejected taking the shots. She is now 32 wks and on complete bed rest due to having a weak cervix. I don't know if it really is the progesterone but, I'll do it again in a heart beat. The only cons I have with the shot is that I have weekly shots which do hurt sometimes and I get itchy at the location of the shot. There are ways to subside the pain and bump by massaging the area after the shot and placing a heat pad. The itching went away after the first 4 shots. Hope this helps and good luck on your pregnancy!

cbonita- I am 6 weeks with my 4th pregnancy I have one DD age 5 ( 2 MC's) My OBGYN has me on 600mg of progesteron a day now Istarteditthe day I got my BFP, Im taking oral tablets 200mg 3 times a day and theonly side effect I have is some dizziness but nothing major. My OB also said that if our baby is a girl she may have enlarged (slightly) genitalia at birth due to the extra hormons but it would only be temporary! Good Luck!! Hope this helps a bit!!

I am almost 15 weeks pregnant and my Dr wants me to start progesterone shots at 19 weeks I have had 4 miscarriages and 2 live births both were premature at 32 and 34 weeks. I spent a month in the hospital with both and that is something I don't want to go through again. Has anyone had progesterone shots to prevent preterm labor and were their any side affects? This is the first I've heard of these shots My kids are 9 and 10 this was not an option back then.

KROGERS- yes, low progesterone can be fixed. I take two progesterone capsules a day (one at night, one in the morning). They can be taken orally but apparently are not as effective, so I take them as vaginal suppositories. I start taking them on CD14 (or when you know you've ovulated) and keep taking them until you get a bfp (and then stay on them until about 14 weeks) or until your cycle is late and you get two bfns. Some people don't get their period until a day or so after they stop taking the supplements. Your doctor will obviously be the best one to tell you what your body needs and what will be the best for your fertility. All the best!

Ok question. Didnt know where to post this. We are ttc. For the last 2 months I have started spotting on day 24 of my 27 day cycle. I normallly ovulate on day 14. My breasts have also been very tender. Doc is checking me for low progesterone. Has anyone experienced this? Is it easily fixed? Can I still get pregnant this month? I am charting and I have a clear thermal shift after ovulation and my temp does not drop till the day before I start my period. Any advice would help. Thanks

My nurse called and said my levels were at 0.97 I don't know if that is good or not. My doctor hadn't looked over them yet but my nurse just told me what they were. Not sure what to take away from that. I am not pregnant but ttc and have had 4 losses and thought low levels might be causing them.

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.

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.

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 - 242 days ago.

I was on progesterone suppositories for my first trimester. I also had a friend who was on them for her first trimester too. I have a healthy 6 month old baby girl and my friend has a healthy 1 year old boy. So, progesterone is there to help, not hurt baby's growth.

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!

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.....

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......

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.

mom2bewithnumber3 - 407 days ago.
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?

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?!?!?!
