Okay so I missed a day on my birth control pill last week and doubled up the next day, and because of that i have had breakthrough bleeding for about a week. Well yesterday me and my boyfriend had sex and he came inside of me... i wasnt able to take my pill yesterday because i lost my pack, therefore i am still unable to take my pills (keep in mind that yesterday would have been three days b4 i would have started my period, im suppose to start on monday) i understand that sperm can live inside of you at a maximum of 5 days, therefore i can get pregnant within those 5 days. but can i get pregnant while im experiencing breakthrough bleeding? i just need some insight please!
