Maybe you should take a blood pregnancy test. good luck
Because its been almost 2months and No AF, I think you should make appt with your Ob....I think you have waited long enough
I got my period first period only a week ago after stopping b/c Mar 29, so I don't know how the next one will go, but I'd see the gyno, maybe you are prego and the test isn't showing it. I had a friend who didn't show up on a hpt or blood test until she was 17 weeks.
