Clear blue VS. First Response???

Tricia • Mommy to 2 handsome boys 💙 and a beautiful little girl 🩷

I’m very confused, I’ve taken about 4 different first response tests and they have all come back with very faint lines. However I’ve taken 3 different clear blue tests and they have all come up negative not even a faint line... 😩😭😳 AF is due tomorrow according to Glow I’m just so confused as to what is going on 😭
