Im 22 years old and 8 months pregnant and having loose stools, lower back pains,and pressure in my lower belly. Ive had the loose stools for maybe a week or 2. and the back pains just started maybe a couple of days ago. I tell the docs my problems and they say drink more water. I go through 2 24 cases of water less than 2 weeks. I was hoping to get some opinions from others possibly that had the same problem.
