I am on my sugar pills. I start monday and usually get my period by wednesday. I had sex with a condom on the monday because my period didnt come yet. He thought some might have gotten inside of me so i took the plan B on the tuesday about 12 hours after sex but a day before my period was suppose to come. Its now late friday night and no sign of my period. I have been on birth control for about 2 years and im extremly good with taking it. So the pharmacist said that between the plan b, being on my sugar pills and my good habits of taking my pill im fine. But the thought of not getting my period scares me. Is my period just not coming this month? And when im suppose to start my borth conrol on monday (its friday night now ) do i just take it and wait till my next period?
