I don’t know what is happening

Jj

I had sex a couple of days ago (unprotected and I am on the pill but it has been inconsistent so idk if this is why I’m bleeding) but ever since, whenever I use the restroom there’s a little blood. It never gets on my underwear but it’s on the toilet paper and is usually gone with one wipe. I haven’t noticed my urine smelling bad or anything so idk.. it honestly feels like I’m on my period but if I was.. it would be all over my underwear

(The heaviest it has been)
