I had intercourse in march the I took ipill after 1 hour of intercourse my periods got delayed in April so I took Meprate and i got withdrawal bleeding that was heavy to light In May I didn't took any medication and got my periods and I was concerned so i took around 5-6 pregnancy tests they were negative. In june again my periods got delayed by 10 days and i again took Meprate but didn't complete the course i took only 1-2 tablet after that I felt a sharp pain in my lower pelvic region and i got 6 days of periods . Should I be concerned about pregnancy?? Or there is no pregnancy? Can I be pregnant or it's just harmonal imbalance?? Please tell me I am really very worried .
