Ok so me and my boyfriend had sex on the third day of my period which lasted about 5 days. We used a condom but all of a sudden he stopped, pulled out, and then pulled the condom out of me. He said that he saw the condom on the tip of his penis so he pulled out and when he did the condom was left inside of me. It's been 75 hours since it happened and I know that next choices effectiveness is reduced after 72 hours. I don't know if I should take next choice or if my chances of pregnancy are low that I don't need too? I asked him if we were okay and he said yes which is why I did not take next choice sooner but now I'm stressing out thinking I should have but it's too late.
