hi my bf and i dry humped naked about a week ago and actually that is the around time i should have my period and now its 2nd of Oct and my period is still not here, could i be pregnant? my vagina was on top of his penis but there was no penetration, though im not so sure if he cmmed or not. also my period last month was also late for around a week, i think it was due to stress. could the delay with my period this time be the same reason, stress? because im having exams and i have been lacking of sleep. or is there a possibility that im pregnant? your response would be much appreciated, thank you.
