i had sex on may 19th, sunday at 6:00 pm. we 100% used protection but i am not sure if the guy took off the condom after he already came and then put it back in me and kept on going or not. im super worried that he got sperm in me. i ended up buying plan b and took the pill. this was 3 days after i had sex and when i only had 2 hours left to take the pill. when i read the box, it said “ the faster you take it the better it works “ so i don’t know if i am pregnant or not because i am 2 days late on my period. am i pregnant and will the plan b still work even if i took it 3 days after? please help.
