i am 17. i had somthing which is not exactly what you call sex with my boyfriend. we were close but he never penetrated. and we were close for just around 10 mins. after that day i have been having membranous discharges (very little and in shreds) with my urine. i have also been having clear vaginal discharges (which i thought to be normal) in increased amount. on 24th my periods were due but it didn't come. i am completely freaked out. is it possible that i am pregnant? i usually have painful periods due to sedentary lifestyle and this month i have been having period pains all through this week but no periods yet. i feel nauseatic and weak but don't have increased urination of vomiting. i am confused whether this is just premenstrual syndrome and my menstruation is delayed because of stress and tension or am i pregnant?
