Did anyone take magnesium during their pregnancy to help with Braxton Hicks and/or leg cramps? I'm 28w2d and I get painful leg cramps pretty much every night. I also tend to have an irritable uterus that gets crampy or BH frequently. I try to stay hydrated but I require a LOT of water. I saw that some women take magnesium to help with both BH and leg cramps... have you tried it? did it help?
