6DPO Sharp shooting pains in uterus. Sign?

Ashley
Has any of you ladies experienced these shooting pains in the uterus? Today I'm 6 DPO and I've had these pains since yesterday. Yesterday I also experienced a vibrating sensation in my uterus. I'm also constantly hungry and my left breast is a little sore. Could this be a sign? And how many of you felt these pains before a BFP
