Dye stealer tests, how many dpo were you if you carried on testing?

My test line has been darker than my control line since 10dpo, is that normal? Everyone else’s tests seem to have faint lines. I don’t think I got my ovulation dates wrong through bbt because that already has me set as ovulating on day 12 which is so early for me I usually ovulate between day 15-17. I’ll upload my chart and 10dpo test and today’s test 16dpo, I’m still testing because we’ve had chemicals, we’ve never seen dark lines like these though 💞
