Up & Up (Target) pink dye hpt, false BFP?

Has anyone had any experience with these tests? I took these three today at different times. The first one was FMU but pic was taken about 20 minutes after. The second one was afternoon but pic taken about 20 after also. The third one was tonight but pic was taken about 2 hours after. All the FRERs I've taken stayed negative. What do you guys think? I'm on CD51 and I'm dreading getting a clear BFN on FRER if I decide to take one tomorrow.
