I had then too, but since I started taking a calcium pill with dinner they've gone away. My theory is that my body is pulling calcium to build tiny bones and is snagging it from my muscles first since that's easier than taking it from bones. I was drinking plenty of water so I knew it wasn't that.
Same !!! With out fail atleast twice a night in each leg my leg cramps then goes into braxton hicks in my stomach its terrible advice I got last night when asking was drink more water and eat plenty of bananas... hope it gets better for you, I feel your pain and its not fun :)
