Heartburn is very common in late pregnancy and completely normal. For safe, quick relief, antacids containing calcium carbonate are the preferred first-line option. Antacids with magnesium hydroxide or aluminum hydroxide are also generally safe. Please avoid products containing sodium bicarbonate, as they can cause fluid retention. If these do not help, H2 blockers like famotidine may be used under medical supervision. To help your sleep, try eating smaller meals, avoiding food for three hours before bedtime, and elevating your head with extra pillows. Always consult your OB-GYN before starting any new medication to ensure it is safe for your specific pregnancy.

The burning sensation you are experiencing is likely heartburn, which is very common in the third trimester. For safe, immediate relief, you can try over-the-counter calcium carbonate antacids. Lifestyle adjustments, such as eating smaller meals and not lying down right after eating, also help. If antacids do not work, your doctor may suggest an H2 blocker like famotidine. Please consult your OB/GYN before starting any medication. Note: If the pain is severe, persistent, or accompanied by headaches, vision changes, or swelling, seek medical care immediately to rule out pregnancy complications.
