AF due tomorrow!

Naomie
AF is due tomorrow and I really don't want to test until after AF is late because I've been way to obsessed with testing knowing that it's too soon to test and ill get a negative. But the anxiety is killing me. I need to know!!! I'm feeling a little crampy on my right side today and back pains. Could it be that AF is coming in time? 😭 has anybody experienced any particular symptoms a day before AF was due and got a BFP?
