Welcome to HealingWell!
There are several things that can cause right side abdominal pains. A few of the most common are:
If your pain is so bad that you can't move, you MUST see a doctor. If the problem is your appendix, it can be life threatening if it bursts. Same as an ectopic pregnancy, it is serious business. Are you in school? Can you go to the school medical facility? Can you get a friend to drive you to the doctor/ER?
