Clear Blue Digital Accuracy

I just wanted some insight to see if any of you ladies out there have been mislead by the clear blue digital test for the weeks estimator? A little back story, I am currently 5 weeks and I took my first CBD last Saturday (Dec 19th) and it showed 1-2 weeks. I took one this morning with FMU and it still showed 1-2 and it should be 2-3 weeks now. I've read some other online threads and it seems that these tests are not too reliable for the weeks estimator. Frustrating!! Any thoughts out there??
