When to use a weeks estimator test?

Brittany • 21 years old, ttc for baby #1 miscarried at 9 weeks! God has a plan!
I just took 2 test an it's obvious there postive but not very very dark, my question is when should I use a weeks estimator test in the morning or a few days? Or should I just get blood work done? Reason askin I had a mc before and I want prenatal care ASAP.
