My boyfriend and I had sex twice on the 4th of October. I took the plan b one step pill in about 13 hours from when we had sex. According to my menstrual cycle app, that is the second day of when I am suppose to be fertile and predicts that I will ovulate on the 6th. What's my chances of getting pregnant after taking the pill if I had sex while fertile???
It's really difficult to say, unfortunately, but I'd still say the odds are in your favour.
Taking Plan B 12-24 hours after unprotected sex still gives around 85% protection. So there's a 15% chance of pregnancy.
If Plan B is too late to stop ovulation, then it is thought to protect against pregnancy in 2 additional ways. It may prevent the sperm meeting the egg (ovum), & it may make the lining of your womb unsuitable for a pregnancy.
All in all, I'd say you've little chance of becoming pregnant. I've had to use it on ovulation in the past, & never became pregnant. That's not to say no one will, but should hopefully put your mind at rest a little.
