Anyone had similar

Atlanta

Currently 6/7 dpo and have had cramps that feel horizontally almost, I’ve been so nauseous and actually thrown up multiple times. Sore breasts and I’ve had headaches all since 3dpo. I know it’s too early but I just don’t know if this is my sign that I’m pregnant? Did anyone experience early signs and turn out pregnant, I know it’s probably just progesterone surge
