Idk bfp?

Alycia
So in the past i have taken several text no matter the price to determine my pregnancy. So after a week or two of questioning myself i have decided to get a discount store brand and got a bfp i told my husband. But am i wrong for just waiting on my tuesday dr appointment? Im like really nervous about it. Its defintely what we want but a part of me is afraid that i may not be! Is there even a such thing as a false positive? Or how accurate is a dollar store brand?
