Cramping?

Niki β€’ 29yrs old πŸ€ married 4 yrs πŸ’ together 8 yrs πŸ’‘ TTC #1 for 3 yrs 🀞
My husband and I are TTC. I am currently 7 DPO. We had sex throughout my fertile week. AF is supposed to start on Oct 2, but I am having light cramps. I will wait to see if AF comes to take a HPT. Has anyone else had light cramps so early before their AF arrived? Is it possible the cramps are the beginning stages of pregnancy?
