Body confusion

So i have no clue what’s going on. I’ve been having sex recently which is never a problem and then yesterday hours after one of our roundabouts, I noticed I was bleeding a little and had some discomfort. The rest of the night my stomach was really bothering me. And then today I woke up and there was a little more blood and after a few workouts i finally sat down at home and the discomfort has gotten so much worse and has started to hurt i still have some bleeding. Does anybody know what’s going on?
