Not a BFP but thought this might be a good group to ask!

So I try really hard not to symptom spot and I’m usually pretty good about it lmao. I’m 8 DPO and I started feeling a cold coming on in the middle of the night last night alongside some AF like cramps. I only cramp the day she shows up and it’s too early for that so I know it’s not her coming:). I noticed today that the roof of my mouth is now sore and hurts to touch. I feel like I might have a canker sore too, but I can’t see anything.

I am probably just crazy, but has anyone had this and get a BFP???
