During pregnancy, especially at 7 months, it is important to be careful with medicines for loose motions because some drugs may not be safe for the baby. Loose stools after outside food are often due to mild food infection or stomach irritation and may improve with rest, fluids, coconut water, ORS, and simple homemade food like rice, curd, bananas, and toast. Medicines like Norflox and Lomotil should not be taken without a doctor's advice during pregnancy. The safest approach is to stay hydrated and monitor symptoms. If you develop fever, vomiting, blood in stools, severe stomach pain, reduced baby movements, or signs of dehydration, seek medical care immediately. Your gynaecologist can decide if any pregnancy-safe medicine or antibiotic is needed after evaluation.
