I was concerned too about taking progesterone supplements, they have all these warnings on the bottle about brith defects and stuff. But apparently we take them at such a low dose there is no effect on the fetus and women have been taking it for years during pregnancy. I think it says it may cause cleft palate and abdominal defects so during my u/s I had them check specifically for that and everything seems good so far!!
I would much rather risk that then to lose another baby to m/c. I believe it saved this pregnancy!
My dr told me to take it soon as I get pregnant.....it keep your progestrone up so that your cervix will stay closed and help to prevent miscarriage
Prometrium is progesterone derived from peanut oil. My doctor prescribed it to me as well. I often wondered the same thing. Many, many women on these forums have taken prometrium in early pregnancy to increase progesterone levels. I read the warnings too and was concerned with the pregnancy warning but my doctor assured me that it can be taken if prescribed to sustain a pregnancy. It turns out that I didn't need it but my fears were the same as yours.
