Is this normal ?

I just came back from a 5 day flag football tournament. As you can imagine there was loads of running and breaking out of normal routine. It was also a 13 hour road trip there and back. My period was due for the 7th if this month(the day we drove back) and I felt the day before that I’d get it for sure. It’s been two days and I’m only bloated and have small cramps. I should mention that during my trip (2-7 of this month) the first two days I was having chunky white discharge in my pee and underwear. A couple days b4 I left for my trip I had gotten a yeast infection, so I assumed it was either that or just regular discharge that I get b4 my period? Other than a lot of physical activity and the infection why else could my period be 2 days late? I also have protected sex days prior to leaving so I’m sure it’s not pregnancy ??
