Im currently 19 weeks pregnant and have been experiencing intense back pain since 18 weeks began. Its generally only on my right lower side right above my hip but in the back if that makes sense.. Anyways the pain is horrid and often times i cant take deep breaths because of it. It'll go on for hours at a time then gradually stop. Should i see my doctor about this? I have an appointment on the 3rd for something unrelated but should i see them sooner or is this normal?
