Can the pain I'm experiencing be from dehydration?

I got dehydrated a lot when I was pregnant with #2 and went into premature labor because of it. At 17 weeks my baby was still moving a lot so the baby could have already moved from the left side. The best thing for you to do would be to go to your doctor and let them check you out. It's better to be safe than sorry!! Good luck with everything and I hope you feel better!
