Okay I take birth control pills and on Friday of last week I had intercourse with my boyfriend and he accidentally came inside of me that night i took my birth control pills but my pills were finishing and it was my last week of “white pills” so Saturday night I didn’t do anything else but take my pills and Sunday I decided to also get a plan b just to be safe. Yesterday i was supposed to get my period but it hasn’t come I’m afraid I might be pregnant
