I took unprotected sex last august 11 around 2pm.. it took 5 mins. only since its my first time too. Then 11am of august14 I took 4 tablet of nordette then after 12 hours, i took the next 4. Im scared because until now, I dont have any bleeding as a sign that it works. Plus, i think i was fertile when we did it but my boyfriend did not ejaculate at all. Is there a big chance that I'm pregnant?? Help me please!
