4 days late bfn

Katelynn
We didn't stress over it this month. We just had sex with preseed, I temped and hoped for the best. My temp yesterday was 97.98. 
4 days late, can't sleep, (tmi) diareah so much so that I had to run to the bathroom at 4 in the morning lol, white discharge, somewhat cramps, so on and so on. 
Do I need to just wait it out, it sucks getting a negative.  :( usually early for my period. Never late?
