Had protected sex 2-5 leading to ovulation. partner used a condom & he took it off. had no precum/ejaculate on his member. finished with a fresh condom on & pulled out with condom on. took plan b within 24 hours later. what are the chances?

Plan B, which is sometimes referred to as the “morning after pill,” is emergency contraception which you take within 72 hours after unprotected sex. The sooner it is taken the better it works. So there is very little chance you are pregnant from the episode you described. But in the future you should try to always practice well protected safe sex when pregnancy isn’t desired. I wish you well!
