Normal or...?

I'm almost 16 weeks. I see my Dr. tomorrow afternoon. I just had cramps so bad they woke me up out of a dead sleep and I was soaked in sweat. I drank some water, used the bathroom and am laying back down...but is that normal? FTM here so I have no idea what to expect or what to consider "normal" or when to genuinely be concerned. I have high anxiety in general so I'm trying not to panic & exacerbate things. On a scale of 1-10 I'd give them like a 3.
