So I have now been on
Prometrium (orally, 300mg a day) for about a week. I have looked it up on the web, and all the sites related to it say to take it before you are pregnant, but not to take while you are pregnant. I am completely confused. My OB prescribed it knowing absolutely I was pregnant, and has me on it up until the end of the first trimester. Also, it seems the symptoms mimic pregnancy symptoms. Has anybody had a negative outcome using this drug?
