WARNING FOR WALMART 88cent first signal

The top picture was my "bfp", yesterday (10dpo) with my FMU. The bottom pic is my bfn today at 11dpo. Either I happened to get a highly sensitive Walmart first signal test or it's a false positive. How heartbreaking. I know it's still early and there's still hope, but there's nothing more heartbreaking than a BFN after the joy of a BFP. 😞 I've read of other false positives with his brand.
