I finished my Clomid doses yesterday (took them as directed days 5-9). They told me to start taking an OPK once a day starting on day 10. So this morning I took my first OPK and it was either positive or very close to positive. I was so surprised because it is only cd10. I called and left a message with the RE's office. But then I read online that if you take an OPK within 3 days of finishing Clomid it can give you a false positive. So now I'm not sure what is happening... I guess I will wait for my doctor to call back but I hope this isn't going to mess anything up. We were supposed to do a trigger and IUI. Did this happen to anyone else?
