Looking for reassurance 😔

Got a vfl (definitely there) yesterday on three different brand tests. Tested afternoon with 4+ hold. Maybe 1pm. Tested today FMU and barely there. I did drink two bottles water before bed. Do you think this had an affect on it? Trying to remain calm.

Update: I can see it again on this one without squinting. If these are evaps, they are the most convincing ever. I dipped a FRER too (why 😫) and it has the faintest looking line/indent, but still there 🤷🏼‍♀️. I guess I just have to wait!
