I have been on the birth control, Ocella, for 3 years. Periods always fall on the exact same days, every month, and I never have had breakthrough bleeding or anything go wrong. I was on an antibiotic at the beggining of last month and I had no clue that could mess up your pills. I have a normal 28 day cycle. My period only lasts Monday-Thursday on my period weeks but are very heavy. My last period was August 23. I had sex the day after my period stopped, and the rest of the weekend; the 27th, 28th, and 29th. It was unprotected. I didn't think anything of it. I didn't think you could get pregnant right after your period. August 3rd I started getting weird spotting. It was a light red, brown and even black. Alot didn't come out but I had it until yesterday, the 6th. I have been getting cramps, my breasts have felt swollen, i've been bloated and tired; but these could also be period symptoms. I'm due to start my period in a week, but I'm kind of scared. Could this mean I'm pregnant. Would birth control hurt the child if I am pregnant? Should I stop taking my birth control until I find out? Please help, i've never went through this and have no clue what to do!
