I thought this might be interesting /helpful!
I got an absolute squinter yesterday at 8DPO.
This morning a noticeable line, both with Wondfo.
I needed to make sure they weren’t faulty tests or something so I’ve been this morning to get a Superdrug 5 days early and a Boots 5 days early, plus Superdrug digital. My cycles have been slightly irregular lately, they went from 26 days bang on for years to 34 and 32 days these past few months so I’m not exactly sure when I’m due on.
Digital was a no but I kind of expected that.
Wondfo definitely clearest followed by probably Boots and Superdrug equally.
