Suggest Remedy For Lower Abdominal Pain

I have right hand side lower abdominal cramps but dont have my period I went to visit my GP last week and she has referred me for a scan which I have in 3 weeks, I have had the pains now for 4 days and they are not improving, I dont know what is the best thing for me to do, should I take pain killers and wait for my scan? Or do you have any advice for me?
