Is BioIdentical Progesterone safe during pregnancy?

by Jami
(Fruita, CO)

I have been taking 100mg of bioidentical progesterone for the past year. My family doctor prescribed it because he said my progesterone levels were low. I just recently found out that I am expecting. I asked my OB/GYN if I should stop taking the bioidentical progesterone and he said I could continue taking it, however, my family doctor that prescribed it said I should stop taking it.

I am now confused. Can bioidentical progesterone hurt the baby? I don't know who's advice I should listen to and I don't want to do anything to harm my pregnancy (I am high risk already due to an incompetent cervix).

Thanks for your help!

Is BioIdentical Progesterone safe during pregnancy?

Hi Jami. Yes it is safe, but if you have had or could have a threatened miscarriage you will need about 200mg/day. I'm currently helping three women who have had miscarriages, all are using Natpro at 200mg/day. The one woman had a healthy boy about two months ago, she used the cream for her entire pregnancy. The other two are only a few weeks pregnant and doing well. You should now be using the cream daily and not follow your cycle! Please see this web page.

I'm a bit concerned you say you're 'taking' the progesterone. You should be aware oral progesterone is mostly destroyed as it passes through the gut and liver. Please see these papers:

Take care, Wray

Yes, you can be on progesterone, even if it's not bioidentical, I know a couple of people who had a lot of miscarriages because their progesterone levels were too low. I found this website helpful when looking for articles about bioidentical progesterone...
