Was my clear blue test accurate? Please help!

BlissfullySweet • Married to my awesome husband 💑👫 Mommy to my precious boy 💙😘👦🏻and 2 sweet girls 💜💜😘😘🧒🏻👶🏻. Baby #4 (the finale) due August 2021. 👶🏻💙🙏🏼
First day of my last period was June 18. I tested with FRER at 9 dpo and got a bfp. I'm pretty certain I implanted at 7 dpo. This past weekend on Saturday (11 dpo), I took a clear blue digital and it said pregnant 2-3. Only thing is, that would make me more like 1-2 weeks since ovulation day was 12 days prior? Why would it say 2-3? Or I am just not understanding how the clear blue test is calculated? 
I've also noticed that people who are at the same week/day as me along with same due date have gotten 1-2 weeks on their tests. 
I'm so confused.
