Why is Clearblue Digital trying to stress me out???

I've taken daily pregnancy tests and all of them have gotten progressively darker. But all of the Clearblue digitals STILL say 1-2 weeks (which puts me only at 3-4 weeks pregnant). I turned 5 weeks today. I know I didn't ovulate any later. My husband and I only BD 3 days last month and not even one time since. He's been out of town, and when he came back a week ago we are both scared cause we mc 2 months ago and started bleeding with it the morning we had sex. So we are just holding odd till we know everything is okay. Anyway...all of my tests have gone from faint to very dark. Except my clearblues won't go to 2-3 weeks! Anybody else have this issue?? I am terrified I'm going to mc again! :(
