I was diagnosed with PCOS in 2013 started metformin 500 mg twice a day I think it worked and even though I was getting negative results on the ovulation test got pregnant in 2014 but sadly had an ectopic pregnancy had one of my tubes removed. Now I'm depending on one tube. Me and my husband trying again but no luck still taking metformin. Has anyone else gone through this and got pregnant? Does anyone know if PCOS causes ectopic pregnancies?
