Metformin??

Hi everyone! My husband and I have been ttc for 10 months now. I went for my annual checkup back in February and told my obgyn what was going on and she started running test. She started me on Metformin a week and a half ago. They also increased my thyroid medication (hypo). They checked my prolactin levels this month and I will go for a progesterone test next week. My husband's sperm count was also on the lower side but the doctor said that should not be an issue. Has anyone else been placed on Metformin? I have googled every possible thing on this medication. I just felt maybe feedback from other people would help keep me positive. This is becoming a very tiring journey. I pray for those who have been ttc for years.
