You might not have been far enough along when you took the name brand or you werent producing enough hormone. I took a dollar store test and it gave a VERY faint line so the next day i used an EPT brand and sure enough:) the only way to be sure is to take another test or go to the doc!
I took three name bran before the dollar store then two after.
If you took the dollar brand one after the others, then it may very well be accurate. Depending on when you took the name brand ones, you may not have been producing enough of the hormone yet.
I took a .88 one from walmart and it was positive 2 days after implantation bleeding, 4 days before expected period. I wound up having a chemical pregnancy though :(
Mine was the 88 cent one from there rhat showed positive at like 4-5 weeks. I am now 9 weeks pregnant. (:
Good question. Somebody pls answer cause I wanna kno too. I'm in the exact same boat!
