Hello doctor, i am 23years old and had anal sex for the 1st time with my guy and since we didn't know how yo go about it so it was painful and lead a bit of tear in the condom. We were a bit scared as to what if sperm reached vaginal area. We did it 2 days after my periods ended (monday). So i took unwanted 72 within 2hours. Now after 7 days (sunday) i got bleeding. It's light as of now. But i might go to doctor for checkup. So will the doctor get to know if i had taken pill by any test she does for this irregular period? And can i be free of worry with respect to pregnancy? Kindly help.
