"i had unprotected sex several times and i wasn&#039;t on bc, although my partner did pull out in time. i wasn&#039;t educated and i didn&#039;t think you could get pregnant through precum. anyway, i took levonorgestrel two days in a row (mexican off-brands), within eight hours of having sex both days. i didn&#039;t notice any side effects the first day i took it, but the second time i felt very nauseous and had a headache. for the next two weeks, i experienced nausea, moodiness, headaches and other uncomfortable symptoms. after a week, i had withdrawal bleeding. i waited a couple weeks before taking pregnancy tests and they all came back negative. my period was almost 4 weeks late. when it came, it was the worst. but i&#039;m not pregnant"
