Me and my boyfriend have always used. Protection and he recently instead that I start taking a form of birth control. I began taking my first pills when my last period started; we had itimancy yesterday in day 13 and he used a spermicid condom. However when we finished he said saw blood and showed me I dismissed it and thought it was due to the pill however I later began to bleed like if I was on my period iam goignt to give it a day or two or else iam going to the doctor should I be come concerned I dont feel any pain
