Hello .Before 3 or 4days I was with my boyfriend we were just spent some quality times in our home. We just kissed nd then he did slight anal sex . we didn't intercourse but his penis was around vulva maybe lessammount of precum was touched due to touch of penis nd fingering. MY PROBLEM is that my menstrual date was around 28th of may bt still am not having my periods not even any pain too... Will u suggest me wht happnd? Nd what will I do? Am I pregnant ? Bt how it is possible?
