Late Period But.......

Hi, my periods really regular and didn’t come last month, it’s due tomorrow now after being 31 days late and i’m wondering, if it doesn’t show.. should i go the doctors?? and if it doesn’t show and I go to the doctors, what will they tell me to do?

- Ik i’m not pregnant bc i tested multiple times negative & also went the doctor 3 days ago about a UTI and had to give my pee, although i thought i had a UTI or a Yeast Infection, but turned out the doctor said I didn’t, and to just air out my vagina and drink more water.. I had symptoms like itching, urge to pee but no pee coming out, burning etc...
