I've gotten over the possibility of pregnancy after too many negative tests and a false positive.

It's been 15 days from my expected period, which is really strange because it's usually on time. Unless I was on BC and skipped the sugar pill. (I am not. Stopped BC end of April, got my period immediately because it was the end of the pack) & I feel I should note that I had skipped probably 2 or 3 periods during the 6 months I was on the pill. Furthermore in the past when I've been "flaky" with my BC it never stopped AF from coming on time.

Possible I have ovulated recently or am now? I've had symptoms of AF for what seems like weeks now.
