Omg, I’m so confused

Amorei

My period was due yesterday and it’s today and no period. So one day late and still no period. Took test and BFN I’m so anxious and I want to know. As of now my symptoms are:

-headaches

-pelvic pain

-can that is egg while consistency (heavy) almost every time I pee it’s noticeable.

Anyone in my position or has been in my position. Any input is appreciated.
