my belly been hurting...

Hi, and thanks for your medical question on eHealth forum!

If you have missed your periods then please take a pregnancy test. If this is negative then go for a blood pregnancy test. If this too is negative then other causes of delayed or missed periods will have to be looked at such as stress whether emotional or physical, hypothyroidism, polycystic disease of the ovary, pituitary tumors secreting prolactin, anemia and poor diet, hormonal imbalance, unexplained or sudden weight gain or weight loss.

Since your back and belly are hurting, either you are pregnant or are constipated, have too much gas, or bladder infection or pelvic inflammatory disease. Since a confirmed diagnosis cannot be given on net please discuss these possibilities with your gynecologist once. Hope this helps. Take care!
