My bf and I had sex on the 13th day of (counted from the day my period started). My period started on 5th of sept and got over on 11th sept. I had sex on 17th sept. . We use two condoms all the time. However one condom got missing (assume the outer one). we searched and did find. But after six days, yesterday I had massive pain and it came out on its own from my vagina. After sex on 17th within 3 hours I took and ipill too. Are there possibilities of me having any infection or becoming pregnant?
