"i took ella 4 days after unprotected sex. a few days later i had brownish discharge. it only lasted one day. i had a few stomach cramps as well as pelvis cramps and i never had cramps before a period. however this also could have been due to how nervous i was that i could be pregnant. my expected period date came around and i missed it. by the 4th day i was paranoid and took a first response pregnancy test. it said negative. on the 6th day i still did not have it and took another pregnancy test and it said negative. i then went to the gynecologist because i was super paranoid and stressed and she said i probably wasn&#039;t pregnant and that the pill thew off my cycle. the next day i got my period. ella does work."
