"i had unprotected sex on april 30, one day after my period had ended, and took ellaone the next morning. i didn&#039;t have any side effects at first, except some spotting, but after about 2-3 weeks i experienced medium cramps mainly on the right side of my abdomen (about where the ovary would be i guess) that got more intense after exercising. the cramps lasted for about four days, but i&#039;m still experiencing mild discomfort in my lower tummy from time to time. i freaked out and took a pregnancy test (20 days after having unprotected sex), which came back negative. my period is due in a few days and i&#039;m hoping all is well, since i&#039;m going on a month-long trip in a week..."
