How long does Advil Pain Reliever and Fever reducer stays in your system? I weigh 184lbs and is a 24 year old female. I have taken two tablets for my period cramping. And when does it start to work? I was skeptical on using it because I read about the side effects but I had cramping in my anal region and lower stomach ( pooch area ) .
