6DPO ?? UTERUS

Christy • Cycle Tracking
I'm on cycle day 22 and I'm 6dpo on a 29 Day Cycle. 
I'm not having cramps but I'm experiencing like DULL Achy, Pressure, and Kind of Sore Feeling inside my uterus it feel kinda full too. I havnt had this feeling during my other cycles. Anyone experience this and gotten a BFP. It do feel like Pms is coming but not exactly the same.
