Okay, so roughly 2-4 days after my period ended, my boyfriend and I had sex. We were in the middle of changing positions when he pulled out, and the condom came out of his penis and was left hanging outside of my vagina. He didn't ejaculate and stated that he didn't feel any precum, but I'm still deathly scared that I'm pregnant. Now it has been 3 days since that day (we had sex on the 12th, it's the 15th), and when I woke up today I had some light spotting. Am I pregnant?! I read online that implantation bleeding is only later, right before my period, but it's only been 5-7 days since my last period?! What are the chances of me being pregnant?
