So me and this guy had sex a day or so ago and he finished inside me but little did I know that my fertile window started and it said that my pregnancy chance was 9% high (which isn't a lot I think) but I am also taking a birth control pill (the brand is Junel). I've been on it for about 4ish months but I sometimes take it a bit later than I should. Should I be worried I'm pregnant or is there no way possible? Thanks!
