AF due date?

Angel
So when I got my positive ovulation test glow changed my AF date to 5/3 from 5/6. My cycles are usually 32 days which would be the 6th. Which day should I go by to test? Took one this morning but it was bfn. Thinking it's just too early, Especially if I go by the 6th instead of tomorrow. What do you all think??
