Feeling....off

I am currently in between my ovulation and next period... that 2 weeks you feel like the world is crashing down on you because of the wait. Well for the passed 3 days I've been extremely tired, I get random cramps in my lower abdomen, weird cravings and then I feel sick if I try to fulfill them, my stomach can't make up it's mind. Recently I've been experiencing being overheated, my face was hot but no fever, so stood in front of my air conditioner. oh and don't get me started on the constant bathroom trips to go pee.. but no uti or infection. Too early to test for pregnancy, so I'm not sure about that one, but wouldn't it be too early anyways to show symptoms. I've had three kids, but never had this (that I can remember). Any advice?
