When did you see your 1st dye-stealer? Is it okay not to ever have it?

Keely 🤰🏼(11w)

I’m 6 weeks pregnant tomorrow and I just can’t stop testing to make sure my body is still making hCG. I’m still getting dark positives, but I was expecting the test line to start becoming a dye-stealer at some point. I’d it a bad sign that it’s kinda leveled out and I’m not getting dye stealers? Shouldn’t the hCG be getting bigger still?
