Cricket - muscle cramps are my only real pg complaint. I swear by calcium and magnesium tabs. They work to stop the cramps in days. Started second tri with DDs1&2, had to start first tri with this bub.

But I had lots of pre labour with DD2, so I'm not sure they made any difference at all there! I think it depends on why you're having pre labour. I'm sure in my case DD2 was getting herself into the best possible position and took a while. Once she lined up, she rocketed on out.
