Just sore/ crampy

So mainly just today I've been kinda sore almost crampy in the whole baby bump area. It's not for a short amount of time it's for 10 minutes or more then it's gone for about an hour or more. When ever I felt this way I drank some more water and kinda layed on the couch which kinda helped. It didn't help that my 2 year old was being a little rotten playing today. Also it was a little painful when the baby moved during the soreness. Anyone else experience this?
