What does your MD say? My RE gave me a trigger shot when I had not ov'ed by day 17 and mid-cycle u/s showed that the follicles were ready. He said clomid suppressed ov in some women, so they need an additional hormone to trigger it at the right time. I have heard that women often ov late on Clomid, but 2 weeks does seem really late. My RE seemed to think it is better to trigger it if it has not happened on its own by a certain point, but many MD's seem to just let things run their course based on the posts on this forum.
