Should I go ahead and test?

Currently on day 37 of my cycle. My period is late 8 days which sketches me out a ton. I’ve noticed I have weird cravings lately along with bigger boobs, stomach is starting to look bigger, my feet have even been swollen which could be from work but just began recently. I’ve been ttc for 7 months each has been failure. I don’t want to test to early and be let down again. Tomorrow will be May 31st and the only thing that I’ve had was a tiny bit of blood that was light pink about two weeks ago which would be a week before my expected period.
