6w4days, still no “dye stealer”?

Montana

Took a first response this morning and my test lines are both dark but no “dye stealer”? With my first born I had a dye stealer very early on.

Trying not to read into it too much… I don’t go in for my first check for another 2 weeks.

Could this be a sign of things not progressing? Anyone experienced something similar?

Breasts still fuller and a little tender, occasional nausea, but new symptom - I’m very lightheaded and dizzy in the mornings.
