Hello, thanks for contacting HCM with your question. You are only seventeen years young and hope your pregnancy test is negative. With the kind of symptoms you are experiencing , sounds like Irritable Bowel Syndrome. This could be associated with constipation, abdominal pain and bloating of the abdomen. Make sure that you have adequate fiber intake daily. Eat whole grain cereal , nuts, fresh vegetables and friuits to get the fiber. Drink enough fluids. Regular exercises would be helpful. If the constipation is bad, you can take stool softeners daily. You can also use PEG solution as per instructions on the package. Hope this helps.
