Pain during sex/light spotting also AF 5 days late

Olivia
So I am 5 days late for AF took a test day it was due but Neg and then two days later but neg again. Going to wait the week and see what happens. Had sex last night and had pain for the first time ever... and then afterwards went to the bathroom and very very lightly had spotted when I wiped but nothing since. What in the world? Thoughts?
