My body is doing weird things and I'm too scared to go to a Doctor.

It all started with my period being 15 days late. Right before I got my period, I got a UTI.

Left the UTI untreated for the Duration of the period. Then on day 5 or 6 I stopped bleeding.

That night I had sex with my BF and the following night as well. 2 days after my period "stopped". My UTI was getting worse, this is like a week into having it, so I went to planned parenthood where I was treated for a UTI. But on that day I also noticed bleeding from my vagina. And it is now 4 days after I noticed the bleeding and I am still seeing some pink blood on the tissue. Anybody have any insight or suggestions? Anything will help.
