A vvfl at 8dpo, negative since...

Got the vvfl at 8dpo on first response (as per pic). Was super excited. Continued to test, mostly got negatives, I swore I kept seeing the second line but probably had line eyes. I'm now day 2 of missed period, negative tests.. I'm never late, always early. Should I put this to the GP and get a blood test if AF hasn't come by day 4-5?
