Hi I am a 15 year old female and lately my body has been acting very unusual. I have really bad lower abdominal pains, this usually happens when I get my period but it happens when I'm not even due or have it. I have also experienced loss of appetite, fatigue from lack of sleep, stages of aggression, pale in the face, lower back pain and a fever. Sometimes I wake up and the abdominal pains are unbearable, please help, what's wrong? What should I do?
