For how long does morning sickness continue in pregnancy?

Q: I am a 31 years old female. The fourth month has just started. I continue to get morning sickness till now. Can you please tell me, for how long does this continue. I also feel very tired, which was not the case in my first pregnancy. Please advise.

A:I hope you have had an examination by an obstetrician. Usually morning sickness subsides after the third month, but in certain cases it can continue for another month or so. Please ensure you are examined by a doctor to rule out other causes of vomiting / prolonged vomiting e.g., hepatitis, reaction to some drug, molar and twin pregnancies, etc.
