8 or 9 dpo

Shakawanna

Glow says I’m 8 dpo and babycenter.com says I’m 9dpo. I’m having mild cramping in the middle of my pelvis. My nose is running uncontrollably. I have headaches that come and go since 2dpo. Anyone on the same cycle as me? What are you feeling? Did you test? Should I test? I’m going nuts here
