Once again, hormones are to blame for another early sign of pregnancy. Changes in hormones cause the valve between your esophagus and stomach to become relaxed. That makes it easier for stomach acid to leak up into the esophagus, causing heartburn.
Heartburn gives you a burning feeling in the chest, just behind your breastbone. The pain can start in your stomach and rise. It can become worse when bending over or lying down. In the final months of your pregnancy, your baby can squash your digestive organs, causing heartburn. It’s possible to take an antacid like Tums for relief. Avoid foods like coffee, tea, tomatoes, chocolate, and fried foods. Sleeping with your head slightly elevated can help reduce your risk of developing heartburn.
