Pain in upper abdomen

Hi mummies! Ytd night I experienced some pain in my upper abdomen, just below the boobs. It's like a pulling pain and it made it so hard to walk. Woke up this morning and everything was fine. Just awhile ago, I experienced the pain again and after showering with cold water, it disappeared (not sure if the cold water had anything to do with it bcos initially I was showering with warm water). Its a kind of pain that can only be felt when I move, breathe in or walk. Is this normal? I'm in my 17th week.
