You can postpone the start of iron supplements till 18-20 weeks and hope the nausea of pregnancy also will be better by then.

Eat healthy and balanced diet avoid oily spicy and sugery food, take iron tablet after food,if no relief please reach out

Hi. Sometimes  taking Susten twice causes nausea and vomiting . You can stop theday time dose and continue at night after food . This will reduce the nausea .

Good evening... -For few patients symptoms will be there till 5 th month or more also. And gases can cause tightness of abdomen -Eat less spicy , and masala food . Drink plenty of water . -Take tab. Zofer 4mg before food twice daily for 5 days .for vomiting to subside . - syrup. Sucral twice daily 15 ml for 5 days. - stop iron and calcium for 1 week and see for symptoms if reduced . If even after the medication if still not reduced see a gastroenterologist.
