2ww symptoms??

I know its a bit early, but im 6dpo and this morning i was surprised by a pulling/cramping sensation in my lower right stomach. It only lasted a few minutes, and happened twice throughout the day. Its now 6pm, and ive been hit with a horrible case of hot flashes, and I'm a naturally cold person.. I may be crazy, is it too early for symptoms? Thankyou!
