It is completely normal to not experience heartburn during pregnancy, especially in the early stages. Heartburn is a common symptom that many pregnant women experience due to hormonal changes and the pressure exerted on the stomach by the growing uterus. However, every pregnancy is different, and some women may not experience heartburn at all. Lack of heartburn does not indicate any problems with your pregnancy or your baby's health. If you are otherwise feeling well and have no other concerning symptoms, there is no need to worry. It's always a good idea to discuss any concerns with your healthcare provider who can provide personalized advice based on your specific situation.
