Should I be worried??

So I just recently started tracking my cycle because we are TTC. My last cycle was 31 days. My period lasts 5-6 days. My period was estimated for July 30. It didn’t come. It hasn’t come today either.

I took a pregnancy test yesterday and it was negative. I am on day 33 of my cycle! Is that normal? Or is that too long? Should I be worried? Does anyone have any advice or calming words to help me?😅
