PLEASE HELP

Last night my boyfriend and I had sex and we used a condom which didn’t seem broken or damaged when he pulled out but when I stood up, let’s just say “it” was running down my leg (which has never happened before). Before I had even gotten up I saw it in places I hadn’t been yet like to the left of me on the sheets.

Is it possible it broke? And that neither of us felt it? Could any damage to it be that not noticeable? Please let me know.
