Has any one tried Clear Blue with week estimator?

Ke
I took a regular test yesterday and it came back positive. This is a pregnancy right after my miscarriage so I don't know what was the fist day of my last period. I was bleeding for a week starting april 16th,then nothing for a month, then started bleeding again for another week. It went away for a week and then I start light to heavy spotting for a whole month which ended July 2nd. When I took the 2nd clear blue test it was positive too but the estimator part said 2-3 weeks but the paper on the inside says your doctor would see it as 4-5 weeks. So my question is who has taken this test and was the week estimator right?
