I'm 21 weeks pregnant and have been having back pains and ligament pains. normal? and also a few days had loose stools but it gone now.

Normal...: With a baby growing and hormones changing, you may have many symptoms that you didn't realize were part of being pregnant. It is normal to have some mild achy back pain and some pain in stretching ligaments. If you have any acute or severe pain, contact your OB. Stool patterns can change also. Make sure you are drinking plenty of fluids and eating a healthy high fiber diet. Take care.
