Yesterday I had protected sex with my boyfriend. During that time he had to change the condom because the lubricant was wearing off... I'm just wondering if it's possible for me to get pregnant or possible for the sperm to get inside of me.. he said he was 100% sure that he didn't ejaculate on the first one ... but he did on the second condom .. he said he didn't ejaculate inside of me.. but I'm still worried.
