Help!

So my periods are pretty regular. I went to see my boyfriend (long distance) couple weeks ago and now my period is late. However, we used condoms every time and we do check to make sure there’s no leaks because we don’t want any babies here 👌🏼 then I got a UTI a couple days later. I only had the FEELING

I was pregnant like two weeks later so I took three tests and they were negative. When my period didn’t show last week I took two more tests on Sunday and they were both negative as well. Can the UTI make my period late or..? I felt nauseous the day after my period was supposed to start and I’ve had like the slightest cramping but other than that (which I’m pretty sure was only because I was hungry ) where the hell is my period 😭
