When Does Morning Sickness Start and End? A Week-by-Week Guide
You are counting the days until you can eat toast without crying. Here is what is typical, week by week, what can help while you wait, and when to call your doctor or midwife.
It is 7am. The smell of coffee sends you running, and you are quietly asking the question every pregnant woman asks: when does morning sickness start, and more importantly, when does it end?
If you are in the middle of it right now, you are far from alone. Nausea in early pregnancy is very common, and it is not a sign that you are doing anything wrong.
Quick answer: Morning sickness usually starts around week 6 of pregnancy (sometimes a little earlier), is often hardest between weeks 8 and 10, and for most women eases between weeks 12 and 16. The NHS says it usually clears up by weeks 16 to 20, although some women feel sick for longer. Call your doctor or midwife if you cannot keep any food or drink down for 24 hours.

When Does Morning Sickness Start?
For most women, morning sickness begins around week 6 of pregnancy, which is about two weeks after a missed period. Some women notice queasiness a little earlier, around week 4 or 5, and others do not feel sick until week 7 or 8. A few women never feel sick at all, and that is normal too.
The timing fits what is happening in your body. Pregnancy hormones, including hCG and estrogen, rise fast in the first weeks, and many women notice that their sense of smell becomes much sharper at the same time.
When Is Morning Sickness at Its Worst?
Many women find nausea is hardest between weeks 8 and 10, when pregnancy hormones are climbing quickly. This is often when smells feel unbearable and even the thought of cooking can feel like too much.
If this is you, it can help to know that this stage is a peak, not a permanent state. For most women, things start to get better after it.
When Does Morning Sickness End?
Most women notice nausea easing between weeks 12 and 16, around the end of the first trimester and the start of the second. The NHS says morning sickness usually clears up by weeks 16 to 20.
Every pregnancy is different, so use this table as a rough guide, not a deadline:
| Week of pregnancy | What many women notice |
|---|---|
| Weeks 4 to 6 | Nausea and a stronger sense of smell may begin |
| Weeks 6 to 8 | Symptoms build, food aversions often start |
| Weeks 8 to 10 | Often the hardest stretch |
| Weeks 10 to 12 | Many women start to feel small improvements |
| Weeks 12 to 16 | Nausea eases for most women |
| Weeks 16 to 20 | Usually gone, but it can linger for some |
Why Morning Sickness Can Last Longer for Some Women
Some women feel sick past week 20, and a small number feel sick for much of their pregnancy. It does not mean something is wrong with you, but it is worth telling your doctor or midwife, especially if it is hard to eat or drink.
A severe form called hyperemesis gravidarum affects a small number of women. It is treatable, and asking for help is never an overreaction. See the warning signs at the end of this article.
What Can Help While You Wait
These are simple things many women find gentler. They are not rules, and what helps one person may not help another.
- Eat before you get really hungry. An empty stomach often makes nausea worse. Plain crackers or dry toast by the bed can help in the morning.
- Small bites, often. Six tiny snacks may work when three meals do not.
- Choose cold or room-temperature foods. Yogurt, fruit or a cold sandwich smell much less than hot meals.
- Keep it plain. Simple carbohydrates such as rice, toast, plain pasta and potatoes are often easier than greasy or spicy food.
- Sip fluids little and often. Water, ice chips or frozen fruit can help if drinking a full glass feels like too much.
- Try ginger. Ginger tea or ginger biscuits help some women. Ask a pharmacist before taking ginger supplements.
- Get fresh air and rest. Open a window while someone else cooks, and rest when you can, because tiredness can make nausea worse.
Do not start any medicine or supplement for nausea without checking with your doctor, midwife or pharmacist first. If nothing is helping, they can talk to you about other options.
On the days when food feels impossible, it can help to have a plan. The Safe Pregnancy Eating System gives you a simple plan for good days and hard days, so you always know what to eat next.
Eating Less in the First Trimester: Please Go Easy on Yourself
Many women feel guilty about eating very little in the first trimester. If that is you, you are not harming your baby by being unable to eat a perfect diet right now. Eating less in the first trimester is very common, and appetite often returns. Keep taking the prenatal vitamin your doctor recommended, and let the rest be gentle.
