Quick question!

If women don't drink a lot of water during their pregnancy could that mean a high chance of having to go into labor early?? Only asking because I'm fasting for Ramadan and I'm not doing it like every day but every other day but I just forget to drink water! I'm so busy! I try to drink as much as I can at night but I get so full so fast because my stomach is so small. Anyways I'm not going to fast anymore because I been having some pain.. Please don't judge me because I'm fasting. I know what I'm doing and if I ever feel sick or tired I will eat!
