Cervical Positions - TWW

I know CP is not a good indicator of pregnancy or anything. However, I was wondering if anyone has had a low open and firm cervix at 10DPO and still got a BFP after?

Can your cervix be medium/low and slightly open before implantation at 10DPO, and then rise up and soften?

Anyone with BFP who checked their CP, let me know your experiences!
