I will try to make my story short as possible.?

I have PCOS, my dr induced my period and, af came 3/19/07 my Dr also put me on BC that same week and I started the following week (sunday sarter) well I missed two pills in a row during my first week of pills and did not use back up method, I figure I have PCOS i can get pregnant any way so I didnt worry well it just so happend thyat would be the same time that I would ovulate ( by the way I have ovulated before but never got pregnant) it also would have been the same time that I would have implantation bleeding which I did 9 DPO on the dot but since I just started back on BC control I thought maybe it could be Breakthrough Bleeding as well . it started 4/9/ -4/11 my period is due on 4/19/07 . the spotting started brown ended Pink, what could this be ? it is even too early for a blood PG test. am I just being paranoid?
