Despite the name, morning sickness can strike at any time of day. Up to 80% of pregnant people experience some nausea, most commonly in the first trimester.
Why It Happens
Rising hCG and estrogen levels are thought to be the main drivers of pregnancy nausea, though the exact mechanism isn’t fully understood.
How Long It Typically Lasts
Symptoms usually begin around 6 weeks, peak near 9–10 weeks, and ease by 14–16 weeks for most people, though some experience symptoms longer.
Relief Strategies
- Eating small, frequent meals to avoid an empty stomach
- Ginger (tea, candies, or supplements)
- Vitamin B6, sometimes recommended by providers
- Staying hydrated with small, frequent sips
- Avoiding trigger smells
When to Call Your Provider
Contact your provider if you can’t keep fluids down for 24 hours, lose weight, or suspect hyperemesis gravidarum — a severe form of pregnancy nausea that needs medical treatment.
Practical Relief Ideas
Eat small, frequent meals, keep plain crackers by the bed, stay hydrated with small sips, and avoid strong triggers. Many people find ginger or vitamin B6 helpful, but ask your provider before using supplements. For more detail, read our morning sickness relief guide.
How Long It Lasts
Nausea often peaks around weeks 8 to 10 and eases for most people by weeks 14 to 16, though timing varies. See the first trimester guide.
Severe Vomiting
Contact your provider if you cannot keep fluids down, lose weight, or feel dizzy, as this may be hyperemesis gravidarum. Read NHS: Vomiting and morning sickness.
