I've had 4 ladies tell me they could see a line on the FRER that I posted.
After the first one, I took the test out of the plastic case so I could see if there was a line on it or not.
I didn't see anything, so didn't think much of it.
That's when 2 more mentioned they could see something, so I looked at the test again (that had now dried), and there was a big noticeable indent in it. You could see it better from the non-shiny side of the test strip.
I managed to get a photo of it.
Not saying this is definitely what everyone was seeing, but it could be.
Hopefully AF stays away and tomorrow I'll have a nice big thick undeniable pink line to share with everyone :)
