emergency contraception
"I had unprotected sex on April 30, one day after my period had ended, and took EllaOne the next morning. I didn'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'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'm hoping all is well, since I'm going on a month-long trip in a week..."
