8DPO... O’d on sept 13/14th already...

So I don’t know if my body is just being crazy... I O’d on Sept 13 or 14th already and it was confirmed by a blaringly positive opk test, and I’m currently 8 DPO and my opk tests have looked like this after O day. 1 day after O, it was light, and then it has gone back to being fairly dark like this opk... is my body just trying to ovulate again? or is there a chance I’m pregnant, I took a preg test yesterday and it was negative, but obviously maybe it’s just too early to be testing..... supposed to get my period Sept 28.
