I know this isn’t an accurate way of telling if pregnant or not but I’m wondering who else has experienced this and gone on to get a BFP

I’m 6dpo today Confirmed by OPK’s and Yesterday on 5dpo I had really bad lower back ache and stiffness as well as fatigue and a few low down twinges. I checked my cervix last night and it was low - hard - open and that’s usually how it is pre AF. I have checked again today and it’s now really soft - higher up and almost closed. Could this be a good sign? As I said I know it’s not accurate. But I’ve never noticed my cervix this soft and squishy before. 🙏🏻🙏🏻🙏🏻 praying for my bfp 🌈
