I have had 3 miscarriages in the past 2 years in which was probably due to being diagnosed with PCOS. I had taken clomid, metformin, progesterone off and on over the years. Every time I have used them, I was able to conceive but not able to keep. As stated earlier, I have been taken clomid off and on and have just decided to get on BCP until jan or feb, just to better control PCOS. I had a lapropscopy done and my tubes were clear. The doctor did notice two cysts that he was able to remove as well. But my question is, Is there a reason related to PCOS as to why I am not able to keep the egg but still able to conceive one?
