They use to use mag to stop labor. In fact some hospitals still do. It's the most effective drug at doing it, but it has the most side effects if you use it long term. They normally use it as a last ditch effort to buy enough time to get the steroid shots done and to prevent brain bleeds.
You must be so tired though. In preemie terms, buying the baby 3 weeks is a huge accomplishment. For me, getting past 3cm's is always the hardest. It goes pretty quickly from there. Hopefully when everything starts back up, it will be fast. Wishing for a speedy delivery when contractions start back up. Good luck!
