I am on YAZ birth control. I had unprotected sex this past November 2nd and had my period (or withdrawl bleeding) November 3rd. When I had sex on Nov 2nd I was on my 3rd placebo pill. Being the paranoid that I am even though I had my period the next day I took a pregnancy test November 27th that came out neg. My period is supposed to start sometime this weekend. my question do you think it is possible I became pregnant even though I had my period the day after sex but was on a placebo pill and have a Neg home pregnancy test 26 days later?. I take my meds about the same time everyday. this is my 3rd month on YAZ.........thanks
