Help!

Hi!

Recently I was put on birth control to protect myself and as my boyfriend an I are rather serious.

We are having unprotected sex. He is however ejaculating inside me.

Recently I had a UTI, sorted that out! Everything was fantastic.

Yesterday was a different story, when I went to the bathroom I wiped and little blood came out and it also started to hurt. It started out as pinkish reddish blood. Looked it up and it said it was normal!(however I didn't add in the pain when peeing) Thought nothing of it.

This morning I got a clump of sticky brown discharge and I got rather worried.

My boyfriend and I had sex(unprotected) and there was blood there too.

I need my women here as I'm beyond confused. Anyone experienced this

UPDATE: it constantly burns when I use the bathroom. Could I just possibly have a UTI? What about the brown discharge?
