It is very common to experience gas and bloating during pregnancy due to hormonal changes. For safe relief, you can take simethicone, which helps break up gas bubbles and is not absorbed into the bloodstream. Calcium carbonate antacids are also generally safe if the pain is related to heartburn. Please avoid medications containing aspirin or bismuth subsalicylate. Non-pharmacological remedies like drinking warm water, eating smaller meals, and gentle walking can also help. While this discomfort is usually harmless gas, please consult your doctor to confirm, especially if you experience shortness of breath, dizziness, or pain radiating to your arm.
