Are Clearblue Digital really, really accurate?

[DefiniteMaybe]

Hi all, my AF was due on 30/11 but I've had no sign. AF has been really regular for the last 10 months or so. I tested with 3 cheapy b and m tests on Saturday, Sunday and Monday and they all had 2 lines but the test line was in the wrong place, almost at the start of the strip. So I bought a lloyds own brand test and did that Tuesday and I could see a really really faint + sign, but so faint I couldn't be sure.
So this morning I've done a clearblue digital test and that says Not pregnant, are they really accurate? Am I definitely not pregnant?

CB is not the most sensitive, but it depends which Dpo you are.

Maybe wait another 48 hrs and test fmu with a frer. That should give you a clear answer if you're either 14dpo or when your AF is due.

Best if luck!

They've always been v accurate for me, even before my period has been due.

I like that response mrsbunglescare, I don't know when I ovulated but we only dtd on 16th Nov so 19ish days ago.

Hate CB. I used one on Saturday and the screen went blank - i had a dud! I did everything right. I am 6 wks 4 day post cerazette and needed t check. I have taken a tesco test which was BFN.
