Walgreens Pregnancy test

I went and bought a pack of Walgreens test and another of first response. I've gotten 2 BFN on the Walgreens on 8DPO and 10DPO. Today is 11DPO. I  then read reviews that the Walgreens Tests are terrible and give false results. I know I have the first response tests but I'm scared to use them if they are real negatives. Anyone have any opinion or reviews to share on the Walgreens tests? Or any other brands?
