morning after post coital bleeding????

had more aggressive intercourse last night. probably should have used lubrication.

this morning i go to the bathroom, and notice a fair amount of brown blood. period isn’t supposed to start until next week. throughout the day light brown streaks just on the paper.

is this just a result from vaginal tearing?? can it last this long? will it go away on its own or is it something more than that.

always used condoms and pull out. plus i’m on birth control.
