What you are experiencing is common, but severe symptoms need careful management. For nausea and vomiting, safe first-line options include Vitamin B6 (pyridoxine) and doxylamine, often combined in prescription drugs like Easypreg OD Tablet. For severe cases, your obstetrician may prescribe stronger anti-nausea medications. Fatigue is normal but can worsen with dehydration. Please consult your OB/GYN before taking any medication to ensure safety for your baby. Meanwhile, stay hydrated with small sips of water, eat small, bland meals frequently, and seek urgent care if you cannot keep fluids down for 24 hours.
