Okay... got my period March16-20. My estimated ovulation period was between March 23-28. (took at home fertility test and it was positive) I had unprotected sex on March 24 and he didnt pull out. I took Next Choice about 22hrs after intercourse and the second pill about 40min late. when i took the second pill i was definitively ovulating. Mind you I get pregnant very easy! Is there a big chance that im pregnant?
