Bleeding

So I don’t really post on here and I feel awkward asking but I need some advice. So my boyfriend and I were doing the deed doggy style and there was a pop noise/feeling that sounded like the condom breaking so he pulled out and the condom was in tact but there was blood and I had a dull pain. Has this happened to anyone else? Was the pop noise from something inside me being torn or ripped? I haven’t bled from sex since the first few times we did it a few months ago. And I definitely didn’t imagine the pop noise/feeling because he felt it too. Let me know what you guys think!
