I had sex with my bf a day after my period ended we used protection and he didn't ejaculate but he removed the condom bc his pens went down so I grabbed it then he put another condom I touched my vagina ignoring that there could be precm ,we continued but he didn't ejaculate inside he pulled out and came on my mouth I was a lil scared so I took an ec pill the next day before 24hrs is there any chance I could be pregnant?
