I am on round one of Clomid (50mg- starting CD5-9) I have taken 1 to 2 opk tests a day since CD10. Most of the tests would show only a control line. Then in CD 16 I had lots of watery discharge/CM and horrible camping that started I the evening and lasted till mid day CD17 here are pictures of the tests which are the only tests that have really shown 2 lines. Could I have ovulated? I'm on CD22 right now and my nipples hurt really bad...although this could be a side affect of the Clomid. Thoughts? Anyone out there conceive with negative OPKs?
