Exhaustion and discomfort

While I'm SO greatful to be pregnant, I swear no one told me I'd be so uncomfortable so fast. I'm 6wks 4days and good god I'm so uncomfortable! I can't tell if I'm urinating more or if it's just more of a pain in the ass to get up and go pee. I'm achey, so crampy and it radiates into my back, exhausted, and the hot flashes!! I have no energy for anything but to toss and turn, no appetite for anything at all. Sorry to bitch and whine, but I just can't believe it's hitting as fast as it is. There's no way I'm the only one though!
