Mommies, i need your help!

2 days ago I was sent to L&D by my Dr because I was dehydrated and it was causing contractions. They gave me 2liters of fluids and I've been drinking Gatorade since I was discharged and I had 1 bottle of Dr pepper. Well, I'm not dilated or anything thankfully (I'm only 29 weeks!) And I figured that all tide fluids and Gatorade would help and I wouldn't really be dehydrated anymore...

Well, I woke up this morning again with my back, sides and front very crampy.. just like I did the other morning when all of that happened.

Could it be something other than dehydration?! I'm starting to get worried that baby boy might end up coming way before his due date...
