"i took next choice one dose after unprotected sex in late dec 2014. i just had ended my period a couple days prior and probably was not ovulating but took it just in case. after taking the pill i experienced tiredness the first day. awful cramps for a couple days after and then started to bleed for about 4 days which seemed like a period. this is a common side effect i read. i was also told if you bleed after the pill, that usually means it worked. my period ended up coming last night which is 8 days after my normal period date. i was stressed the whole time waiting for my period to come. finally it&#039;s here. this pill works!"
