Newbie, did your doctor tell you to stop taking them? My OB just prescribed me prometrium too and he told me that if I am pg that I will most likely be on them until wk 14 until the placenta has taken over.

Hi Katie! My doctor actually told me to stop at week 12...but I was too scared to do that. I was originally on 200mg 2x a day. I was worried to stop it so abruptly, so I took only one dose a day until week 13. But of course now I am worried.

Sam, don't worry you are totally fine! The placenta starts taking over well before 12 weeks (I think it starts around 8-9 weeks) and is fully in charge by 12. If it eases your mind ask your doctor for a progesterone blood test or keep taking the pills for a bit longer as it won't hurt, but really you don't need them for sure after 14 weeks. You are doing great! When was your last ultrasound?

I can definitely understand your worry but since you are now in the 2nd trimester then the placenta should have taken over by now. I would consult your doctor and ask about it. Good luck and I'm sure everything will be ok..

Yes, you placenta start taking over at around week 10. There are already 2 weeks of cushion. I know it's scary, it was for me too, but I tough it out, and stop cold turkey at 12 week. You and your baby will be fine!

STEF, CYNN, KATIE: Thank you girls so much for your words of wisdom. That really helps! I didn't realize that the placenta starts working so soon. My doctor was very confident for me to stop the progesterone at week 12--but I was so paranoid about that. I will ask my docs again at my next appt. I just went in for my first tri. screening test on Monday. Oh my gosh, the u/s was amazing. Baby actually looked like a baby!!! It was wiggling around everywhere. It was such a neat experience to see that since I don't feel any of the kicking yet. When did you feel your first kicks? :)

That's awesome about your scan! To have a good NT scan is a huge step and your chances are very very very low of having problems after that. I first felt movement about 15 weeks but wasn't sure if it was baby or gas. By 16 weeks I could definitely feel it, but i hear that is kind of early.
