Help, i dont know what does this mean...

So me and my boyfriend were having sex,kinda sorta rough but not really lol, and at one point I felt some kind of crack. After we were done I went to the bathroom to pee or whatever and when I wiped I seen blood... it wasn’t a lot but I had to wipe myself 3 times in order to get it under control. So what does this mean? Did I like break my vagina or something😂
