hi there, i was just prescribed Prometrium 100 mg, to be inserted vaginally every night. I have a few questions: 1. I have precancerous cells and i am worried due to reading the warnings that this may cause them to turn to actual cancer cells, will it? 2. i am not pregnant yet and i have to take it up to 16 weeks pregnant, i was reading some reviews online and women said they didnt even get a period/ is this due to the pills? is this going to cause me to stop having a period? 3. i have had 4 miscarriages, what are the chances these pillsd will help? Thank you in advance. M
