A major symptom of Celiac's Disease is bloating and caused from eaten gluten that is found in several food grains. There is a federal website that lists and describes digestive disorders and diseases from A to Z. Go to http://digestive.niddk.nih.gov, and click on the Digestion or Digestive link to read about the many factors that affect one's health in the digestive tract.
Good Luck.

Welcome to the MedHelp forum!
Yes both oral contraceptives and antibiotics can cause abdominal bloating. Take probiotics and see. If the bloating is due to antibiotics, it will settle down. If not, change your OCP and see. If still you do not benefit, then other causes will need to be looked at.
Other than IBS or spastic colon you could be suffering from Celiac Disease/Ulcerative Colitis/ Crohn’s disease, H pylori infection, diabetes, food intolerance, malabsorption syndromes, constipation, gallbladder and liver problems, pancreatic dysfunction, or taking a diet rich in sulfites. Cancers of the gut and in female ovarian cancer too could be a cause.
Please consult your PCP for primary examination followed by proper referral.
Take care!
