2 vfl and then 2 BFN???

Kelsea

What’s going on?? I’m so confused.

These two were taken last night, several hours apart. Both appear positive to me (of course a barely visible line, i see it better in person but its hard to get on camera so I tweaked a bit)

But then today I took 2 more of the same kind (FRER) and both of them are clearly negative!! What in the world is going on?! Please help.
