In May well the exact date may 30th I almost had sex.. yes the penis came in contact with my vagina but I didn’t let him you know go all the way in sooo here’s my problem after that you know next month or whatever and yes I did get my period(the next month) but now it’s July and I haven’t gotten my period could it be that I’m just late or am I having other complications? Any thoughts??(I’m 12 days late )
