M.B.
I had early contractions and was also put on bed rest and medication. My Dr. told me to drink a gallon of water a day at minimum, to keep them under control. It really helped a lot. My situation could have been different then yours, of course. However, I did carry my son until 3 days before my due date. Water is cheap and readily available, you might try!! Good luck, I hope the best for you!!
