We were both virgins and decided to have sex, we used a condom, and before ejaculating inside of her, I made sure it wasn't broken. After I ejaculated I pulled out but the tip of the condom stayed in, most of it got outside of her except the tip. I rapidly removed it and told her to clean herself with some paper towels, just in case. She took a Plan B pill about 3 hours after intercourse. The condom didnt break at all. Is there any chance of pregnancy?
