I have an irregular period. Normally it comes every other month. However, 2 months ago, it was on Feb 10 and last month March 21, falling on the consecutive months. Yesterday, Friday April 7, I had unprotected sex in which a very small amount of cum got into me. So around 25 hours later, I took an emergency contraceptive. I m stressing myself out worrying that I may become pregnant because I ve spent hours on the internet scaring myself. Is it possible that I may have taken the EC during ovulation, this it not working?
