i supposed i had my ovulation2 days before we had unprotected sex, but then my bf did not have an ejaculation inside me. it was only afterwards when he ejaculated on his underwear. i knew about emergency contraceptives but it was my first time to take 55 hours after the deed. i took 4 pills of nordette as a 1st dose and another 4 pills after 12 hours. they say that you can be nauseated and have headaches form taking it but i did not experienced any of it. could i still be pregnant even if there is no ejaculation and i took the pills within 72 hrs?? pls help.. im thinking a lot of things and i get paranoid from this..thanks..
