Is the line too light? Low hcg?

Danelle

It’s been a week since I got my first faint line. The line doesn’t seem to be getting that much darker. Should I be concerned my hcg levels aren’t progressing enough? I had a very very light pink spotting incident this morning but has since stopped. No cramping. I’m 4 weeks 5 days currently. Any advice or help would be appreciated! Thank you!
