Yes you can over hydrate yourself. Have a salty snack and see how you feel after that. Water is great but the more water you drink the more sodium and electrolytes you flush from your body, so you need to make up for that loss.
The more u eat and drink it takes up space, so baby has less space to move, thats prob y u feel him alot. But yea u can over do..becareful
Yes, you can over hydrate yourself. It takes A LOT of fluids tho. If you are in pain i would call your prenatal nurse hotline to ask for advice.
