emergency contraception
"I took plan b within 24 hours after unprotected sex. A few weeks later I got side effects that I figured were from the pill, but they were similar to pregnancy symptoms as well. I didn’t stress about it much, then when my period was late I figured it was another side effect. 10 days of my period being Iate and  finally took a test, positive. I got pregnant even though I took plan b within the 24 hour span. Maybe I was ovulating too closely. I think this medication does NOT work if you’re ovulating or about to ovulate. Keep that in mind."
