AF expected today but not here.

Im a little excited but ive experienced this before... period 3/4days late but negative pregnancy test. my body can be very mean sometimes lol. But okay we used preseed this month and for the last couple weeks ive been experiencing this:
-feeling nauseated 
-eye pain (eye ball) 
-toothache
-sore throat
-ewcm for days straight after ovulation
-cramping on my left side
- & today was my expected AF but instead i get milky white discharge. I know youre supposed to go through implantation and everything but i had no brown/pink discharge or nothing... could i still be in the running this cycle or should i call it quits??
