I Am Having Severe Pain In My Right Side. Started

I am having severe pain in my right side. Started today after not feeling good yesterday. I threw up in the morning after coffee but stopped later and was able to have some soup and peaches. Today this pain is bad and I just threw up again. The pain is closer to my arm pit and hurts bad when I move. I 'm not sure what to do. It's Sunday and i'd rather tough it out and if it's still bad on Monday I will definitely call my doctor.p
