How good are Clearblue Digital??

[bellebaby]

Anyone used these? I got a couple of faint bfps on FRERs and was wondering if a digital test is likely to say "pregnant" or if they aren't very sensitive? They cost $20 and I really don't want to waste money if they only pick up high levels

Note - I am a day late for AF, been getting bfps for about a week yet have a negative blood test 2 days ago (strange I know)

I used it when I got pregnant with my son and it was right the first time good luck
