I suggest making a herbal tea like peppermint or chamomile. That can help with indigestion or bloating. Also avoid high fat and spicy foods, and chew your food slowly…also maybe mixing a calzone with icecream may not agree with your system. If you dont have herbal tea maybe just some warm water with lemon juice might help. If you still have the pain after your period maybe you should see a doctor. Hope you feel better!!!
