12 days before my expected period I had unprotected sex with my boyfriend, even though he pulled out (which I know isn't very effective) I took plan B 23 hours after the incident. 6 days later I had sex again but with a condom if that makes a difference. THEN a week after I took the pill (a day after I had sex for the second time) I had spotting in the morning which turned into a light to medium flow for almost 3 days now. (let me inform you that I wasn't expecting my period for another 4 days) This is very odd because I never spot and my period is very heavy. Should I be worried about pregnancy or is this just an early period caused by the pill? Sorry if this is too confusing to understand
