6DPO & AF type cramps

I’m currently 6DPO, experiencing really strong AF style cramping which I’ve never experienced before, I have 9 days til my period is due, I only usually get cramps the day before, it’s my telltale sign that it’s coming. I also feel nauseas and have been so so tired, I feel like a zombie, all I want to do is sleep. Also have had a lot of white creamy cm since 3dpo and it seems to be increasing everyday. Has anyone experienced this and then gone on to get a BFP?

What are my chances do you think?? TIA x
