SEX CAUSED PROFUSE BLEEDING

last night I hooked up w this girl & she was fingering me and went down on me and as I was cunning I started squirting blood? after that I started bleeding to the point where it was literally dripping out of me so fast and I had to sit in the bath til it slowed down (it’s the next morning and I’m still bleeding). In addition to that my vagina was also kinda swollen? Please help I feel so gross :( I’m almost 100% sure I don’t have an STD bc I got checked recently so I’m basically sitting here feeling like there’s something wrong with me🥺 btw this is what my sheets looked like after
