okay so basically i was having sex with my boyfriend and he pulled out so we could change position and then we noticed that the condom came off. we checked the sheets and on the floor but couldn't see it so i checked inside of me but couldnt feel it. we then got another condom and carried on but he didn't come inside me(even though he had a condom on) almost 2 days later when i was on the toilet the condom fell out. I was really embarrassed at first and then started freaking out thinking that I could have gotten pregnant from the precum in this 2 day old condom. anyone know the chances that I am or not?
