I'm on birth control and for the past two months my period would start 2 days early with brown blood but by Wednesday I would have my regular period so I didn't think much of it. I take my birth control everyday at about the same time and 99.9% of the time I use a condom but last night it broke and I noticed pre cum on his penis and I started to freak out that I could of gotten pregnant. Also I'm supposed to get my period tomorrow and because I didn't get the early brown blood I usually do on Sunday I'm scared. Help.
