I have PCOS and took clomid CD 5-9, got negative OPK but had a follicle US that showed two good follicles and did timed intercourse. As of today I am on 14 days of consistent high BBT.  Any advice??? We had a miscarriage back in November and this was our first cycle. Had a healthy pregnancy with help of clomid and our daughter was born may 2015.
