Clearblue weeks estimator

Need some input. On Saturday the 12th I took my first one and it was 2-3 weeks, Thursday came along and I tested again, still 2-3 weeks but now its Monday the 22nd on the 10th day since I tested and still its 2-3 weeks, so I'm scared. I've had 3 miscarriages before so needless to say I'm scared. Anyone have similar situations?
