I haven't had sex it 7 weeks the last time I had sex was February 16 with a condon had my normal period feb 27 6 days long just like always with same flow as always. Here it is time for my next period (2-3 days late) and I haven't started yet. It acted like it was starting usually really light like it always does on day one but then nothing more...... I don't have a single symptom of pregnancy. No enlarged or sore breasts no darkening of aerolas no frequent peeing no food adversions no weight gain no fatigue or nausea or constipation. I've had mild low abdominal pain like I get before my period but still no period....... What do u think is going on?
