Hi i have a pain in my right side like its a period pains it comes and goes now and then bit worried about it?

See your physician: Not quite enough information present to give specific advice but you should get checked and not ignore the pain if it's persistent or recurrent. Pain is the way your body signals you that something is wrong. It may turn out to be something relatively insignificant. If it's something more serious, early diagnosis and treatment gives you the best chance for a good outcome.
