DR said No more soda for me (caffeine or no caffeine) and I need more water what else can I drink?

Like Juice very much It gives me heartburn and I am not much of a water fan either.. I mean I was literally a soda drinker about 4 or 5 a day and since I got pregnant I drank about 2 a day but I recently went in to the hosp and had a fetal monitoring session bec I was worried I didn't feel the baby all night and in the am so i went in and they said i was having little contractions but did the test to see if I would go into preterm and luckily It was negative I am 29 wks and they told me that I needed to drink more water that i wasn't drinking enough but she had more than enough amniotic fluid and i went for a 2nd fetal session and all is good so.. yea Just need to know what y'all drank while preg lol cuz i sure miss my dp and pepsi even sprite lol.. Please no rude comments;-/
