No period, period symptoms

Sometimes my period is 2/3 days late but I’ve never in my life had no presence of a period. My periods are typically on time, every 28 days. This is going on 5th day with period symptoms - cramping, tender breast, fatigue etc. but no period. The other day I peed and not to be too detailed - sorry if TMI - when I wiped I had a very small amount of light brown colored discharge. I assumed I would get period soon. Now I keep having this light brown discharge each time I pee but no blood at all.

I had a few other odd things happen too... I was getting a ton of UTIs couple weeks back. I took the cranberry pills that make you have to pee and it worked fine but they kept coming back. For about 4 days straight I had to take those pills. Then I read an article that stated UTI is an early pregnancy symptom. So now I’m obviously a little worried.

I did have a very small amount of blood a few weeks back when I wiped but I thought it was from the UTIs and brushed it off. I also did have sex with my fiancé - so there is of course the possibility that I am pregnant, I’m just worried as I don’t want it to be something else... or just no period- that’s never happpen to me before and can’t be good.

Has anyone else had any of these symptoms before?

Thank you!
