Have been pg twice m/c first time, DB second time both through IVF. Both Pgs achieved in a 28 day cycle, but my cycle is normally 30 days (have polycystic ovaries, but ovulate). One Gynae thinks that shortening my cycle length would really help me get pg again. We only have one more attempt at IVF and I am desperate for a sibling for DB. If any one has any ideas for shortening cycle than please let me know.
