J.K.
S.,
I had trouble getting pregnant and ended up at a fertility specialist. During the time in which I was attempting to get pregnant I would have to take progesterone toward the end of my cycle and then go off for three days, if my period started I stayed off but if it didn't during those three days off I would have to take a pregnancy test and start them again. For my first preg. which resulted in a miscarriage the dose was found to be two low. For my second pregnancy we were expecting twins and they did adjust the dose but I lost one and was blessed witht he birth of my daughter. A year later I once again started fertility drugs and this time all went well with the birth of my son. If I remember correctly I had to take them through the first 12 weeks of my pregnancy both times. Maybe seeing a specialist would be best. I had my children at 36 & 37.
