Hi .. I had a blighted ovum which was a natural pregnancy with 4 months of trying ... one chemical pregnancy with clomid second cycle.. one more chemical right after the 1st chemical no medicines . I have pcos. Did anyone have such case and succeeded. Any help would be appreciated . Doctor told we can try one more time and see. Now I am on metformin(no sugar but).. we are not trying now. Feeling anxious to try.
