Any insight?

Megan • 2 first Tri losses, one rainbow baby-Finley James, and one second Tri loss-Eleanor Ruth

I thought I saw a very faint line on a Wondfo test this morning so I went and bought the expensive ones. Both FRER have faint lines but the CBD obviously says “not pregnant”. I know those ones aren’t as sensitive but I’m still second guessing myself....could the FRER be false positives? They do appear to have color in person...not sure if that comes across in the picture. I’d love to hear everyone’s thoughts-both good and bad!
