Clear Blue Digital

I am now 4w 6d and I took a clear blue digital last Tuesday. It said pregnant 1-2. My dr won't see me until 7 weeks (Mar 16th) so I freak out about every little thing. I took another clear blue digital today and it still says pregnant 1-2. Does that mean my levels aren't rising like they should or has anyone else experienced clear blue not changing the weeks estimator? My FRER also look the same. They are just as dark as they were last week.  I don't have those super dark color pulling from the control line tests.
