So..... dye stealer

I've never had a dye stealer because I'm usually not testing all the time. But since I had a miscarriage before I guess I just want to be overly sure. So as of today if I go by my last period I'm 5 weeks 6days. I did a ultrasound last week but they couldn't see anything yet, just a thickened uterus lining which is normal so early on. The first pictures are what I took starting October 1st. The second is today 10/7 at 3:30 pm.
