Testing early with dollar store & CBD

I've gotten a positve result on dollar store tests on 9dpo & 10dpo, but I wanted to know if since I still have 4 days until AF is due, will it show up on a digital test? 
I don't want to waste a 15$ test, but I've already had 3 postive 1$ tests within 2 days. 
The clear blue digital (the one with the weeks estimator) says you can test 4 days before you're missed period but only 65% of women will get a positve result. 
Should I test with the digital test
Or should I wait until AF is due even though I've had Positives??
