Hey girls, I am on CD16 and had a + smiley face OPK last night and again this morning, tonight it was gone. Question is, can we still catch the egg if we DTD tonight or is it too late now? I had SEVERE O pain the last few days (100 mg clomid cycle) and it is still sore in that area tonight. We DTD the last few days but I was just wondering if there is still a chance now that the OPK is no longer positive. Thanks!
