cramping at 21 weeks

bdorley93

This is my first pregnancy so everything is really new to me. I am 21 an my whole body hurts, it hurts so bad to roll over in bed and its ridiculously painful to walk. Also when i wake up at night to use the restroom i get really bad cramps in my abdomen. When i said something to my doctor, her only response was, "You're pregnant, it is not going to be comfortable." I would just like to know if this is normal or if I should be concerned.
