My boyfriend and I had sex two days before my ovulation. He didn't pull out and we did not use protection. I took an Emergency contraception pill 12 hours after sex. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> my chances of getting pregnant were at 33% that day. The contraceptive claims to be effective in 7 out of 8. Is there still a good chance of me getting pregnant or should the EC have been effective
