My obgyn prescribed me with prometrium because there was a possibilty that a hormone in my body was low. The same day he prescribed the meds, he ordered some labs and put me on bed rest and had me schedule a follow up in a week. I got the medicine filled at the pharmacy but wasn't exactly comfortable with taking them because my doctor informed me that prometrium is not fda approved. I decided not to take the medication. When I returned to the doctor a week later, he said that my hormone level came back at 12.4 and informed me that that is extremely low. He said that my body would have had to have produced more of the hormone otherwise I would have already miscarried. (Before the appointment with him, I had an ultrasound done that confirmed everything was normal.) He ordered more labs to make sure that the hormone levels are where they need to be and asked me to schedule a follow up in a week. After this appointment, I decided to take the pills being that the first labs that were done determined that the hormone level was low.
My question is I am almost 14 weeks pregnant and was wondering if these pills can cause harm to the baby? how effective are these pills at preventing miscarriage? Am I still in the red zone for miscarriage even though I am practically in the second trimester of my pregnancy?
Somebody please help because I am really concerned about what could happen.
