Nausea and vomiting are very common in early pregnancy, and they are not limited to the morning. For most women the sickness begins around weeks 4 to 6, is often at its worst around weeks 9 to 10, and eases by about weeks 12 to 16. For some it lasts longer.

Ways to feel better

Medicines that may help

If home measures are not enough, speak to your doctor, midwife or pharmacist. Some anti-sickness treatments, including vitamin B6 in certain cases, are considered safe to use in pregnancy. Do not take any herbal or over-the-counter remedy without asking first.

When it may be hyperemesis gravidarum

Hyperemesis gravidarum is a severe form of pregnancy sickness. It is not just bad morning sickness, and it needs medical treatment. Signs include:

Contact your doctor or maternity unit the same day if you cannot keep fluids down for about a day, or sooner if you feel faint. Treatment can include anti-sickness medicines, fluids through a drip and sometimes a short hospital stay. Hyperemesis is treatable, and getting help early helps you feel better sooner.

Seek urgent care if

You are vomiting blood, have severe abdominal pain, a fever, or you feel confused or faint. Look after your mental health too. Constant sickness is exhausting and can make you feel low or isolated, and it is fine to ask for support.
