I can understand your concern. By your history and description, possibility of HERD (gastroesophageal reflux disease) is more. HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause symptoms of belching, chest pain, nausea etc. Only Chat Doctor.  You should also follow these lifestyle modifications. 1. Avoid stress and tension. 2. Avoid hot and spicy food, avoid junk food. 3. Avoid large meals, instead take frequent small meals. 4. Go for walking after meals. 5. Quit smoking and Alcohol if you have these habits. 6. Keep 2-3 pillows under head in bed to prevent reflux. Don't worry, you will be alright with all these.
