can i ask you a serious question?

It sounds so off. Sex itself cannot cause fallopians tubes to tear.

Rough sex doesn't just involve thrusting, for one. For two, yes, sex alone CAN cause a fallopian tube to burst, but it USUALLY requires a secondary condition as a contributing factor. Three, there are a fuck ton of veins and arteries in that region, why the fuck do think so many women died and STILL die in childbirth and after miscarriages? Because they hemorrhage. Usually inside the womb, but it's not unheard of for the artery that's under the womb to burst, leading to internal hemorrhaging. Four, OP would have either just had surgery after losing a lot of blood when they posted this, or submitted it several days, weeks, months or even years after the fact, meaning that they very well could have misremembered the type of hemorrhage. The medical field is the living embodiment of "if it can go wrong, it will." Don't say something is impossible, because chances are, someone, somewhere, has had it happen.

Internal bleeding, usually when a vein or artery bursts.
