What does it mean

Hey this is going to be a wired question letting you guys know.

But the pass couple of mouths i been noticing that i kept getting some kind of infections and over and over again. No matter what meds or antibiotics they give me.

The first one was a UTI. Hard to pee and a shape pain in belly. Took the meds correctly and no sex until i was done and still waited 3 day after completely.

Then after that I got a bladder infection. Did the same thing as befor.

Now maybe a mouth later. I got the same pain and discomfort as before hard to pee

painful sex

constant pressure and I'll go to the bathroom often. I think i got an infection as befor or something.

Now my questions is what goin on and why is it happen again. What can i do to prevent this from happening. And also is it cause of my bf doing stuff behind my back. Basically cheating.

Or is their something seriously wrong with me that the doctors isnt seeing.

How often is this infection
