About three weeks ago i started my birth control pack( been on it for almost 9 months) however, i was unable to get my new pack on time so i got it 11 hours later and took my first pill 11 hours later.. Since then my bf and i have been having sex often. I just took my last active pill tonight and i start my placebos tomorrow. Last night i had a brownish discharge and i had pinkish red blood today.. It only lasted about 12 hours because now i am not bleeding anymore.. I am very paranoid about being pregnant. The only symptoms are- sore boobs- which i get every time before my period and i broke out a little.. Usually i get my period by now but it hasnt come yet!!! Help?
