Af due today and hasn’t appeared


Af is due today and has not arrived. I’ve not felt right since a week ago. Having pains in uterus and not normal symptoms. My nipples have got bumps on them (tmi) and I have had cramps like AF is coming.. I only have 24 day cycles. Shall I test tomorrow or wait.. I’m 14dpo today.. I just don’t want a bfn if I test too early and af shows up 😞 any advice would be great thank you
