Clear blue connected or one step (cheap red dye) CONFUSED??!!

Rebecca • Due 28 November with our 1st baby - a little girl 🥰

Trying TTC baby #1: So I’ve recently started testing, I have the clear blue connected but it’s a bit intermittent & the one step (cheap red dye) so I use both. Today the clear blue had a static smiley face which means today and tomorrow are my peak fertile days but the one step only had a very faint test line?? Which one do I go by?? Thank you
