Is this OPK TOO DARK??

The test line is WAY darker than the control line. Has anyone seen something like this? Any ideas??? Just worried there may be something wrong. 😢

Breastfeeding 18 month old and everything is inconsistent so I’m trying to figure it out with OPK’s, temping, and cm...I thought I should be 12 dpo today. Negative clear blue digital, so I don’t think I’m pregnant.

Worried and confused.
