Did that happen to you with a faint line berries? It's a bit strange I have to say. Every other time I've been pregnant it's been a very strong line straight away and I think both times that was before my period was due
Well I did another one this morning and got another line. Have since done a Waitrose cheapo ( second MU but hadn't drank anything before) and a clearblue digital with the same sample (dipped them both) and not even a squinter of a line on the Waitrose one and digital says not pregnant. Could the clear blue non digis be giving false results?
There is a list on line somewhere about the sensitivity of different brands, I can't for the life of me remember many though. All I do know is previouslu first response gave me a line 4 days before AF was due. This time I was 4 days late and the line was darker than the test. From what I've read before blue dye tests don't show as easily as pink dye tests.
