Help :((

I’m 11DPO and I’ve literally had NO symptoms the whole week. Which is so out of the ordinary for me because I usually have every symptom in the book when it comes to AF. It works like clockwork. I know exactly which symptom to expect on each day but I feel nothing. Just very mild cramping around 5DPO and a little bit of nausea and dizziness the night of 8DPO, but everyday I’ve had pinching on my left side. I took 2 Walmart tests and they both had a vvvfl but I’m wondering if they’re Evaps. Now I just took a FRER and BFN ;( anyone else experience this? Can it still be too early? (ps AF is (hopefully not) supposed to arrive in 3 days)
