Overly Tired? Maybe?

For the past 4 or 5 days I've had nothing but cramps, they feel as if I'm on AF and I'm not. At least not for another 10 days. I'm bloated which makes no sense, because I've never had a bloating problem before. I'm beyond exhausted in the morning, when I wake up my body just feels heavy, I don't have the energy to get myself out of bed. I always feel cold so I'll cover up or wear a jacket but as soon as I do I feel super hot like I have a fever. I jjst can't win.
