Clear blue digital plus weeks estimator

Cassie
I'm 5 weeks 5 days, and we may or may not be telling our patents this weekend. So I just took the clear blue digital with weeks estimator and it still says 2-3. Meaning actually 4-5 weeks. Should I be concerned that it's not saying 3+ yet? It was with my FMU. Idk if that means my HCG levels are low?
