It is common for pregnant women to experience abdominal pain, especially as the uterus expands. However, if the pain is severe or accompanied by other symptoms such as bleeding or fever, it is important to consult a healthcare provider. In most cases, mild abdominal pain on the left side during pregnancy can be attributed to round ligament pain or gas. The round ligaments support the uterus and can stretch and cause discomfort. Gas can also build up in the intestines due to hormonal changes, leading to bloating and cramping. To alleviate these symptoms, try gentle stretching exercises, applying heat packs, taking warm baths, or using over-the-counter antacids after consulting with your doctor. It is always best to seek medical advice for any concerns during pregnancy.
