When does morning sickness start?

Section: Morning sickness

Morning sickness is one of the main pregnancy side effects that we've all heard about (and we all fear!) 

However, not everyone experiences morning sickness in the same way or even at all (lucky devils!) and although it is unpleasant, it can be a sign that your pregnancy is ticking along nicely. When should we expect this pesky symptom and what exactly does it mean?

When does morning sickness start?

Morning sickness usually starts during the first trimester at about five or six weeks pregnant. It is often one of the first indicators of pregnancy. Morning sickness can range from a general feeling of nausea to vomiting and in more severe cases hyperemesis gravidarum. If you cannot keep food down and are suffering from severe vomiting, it is best you visit your doctor to discuss potential treatment.

Contrary to what the name suggests, morning sickness can occur at any time of the day but pregnant women often find it to be worse first thing in the morning before they have eaten. According to the NHS morning sickness "doesn't put your baby at any increased risk, and usually clears up by weeks 16 to 20 of your pregnancy" around the start of the second trimester.

If you are suffering from morning sickness there are some remedies mums swear by. You can also try to eat small frequent meals, eat something plain like toast before getting out of bed and to drink water regularly.

What does early morning sickness mean?

If you find you suffer from morning sickness before five weeks, this is normal. Some women suffer from nausea very early on during pregnancy although it is not usually accompanied by vomiting. At as early as two weeks pregnant certain strong smells (like perfume or beauty products) or strong smelling foods may trigger nausea. If you have had multiple pregnancies and previously experienced morning sickness, you may notice nausea as a symptom earlier than other women. 

Some believe that early morning sickness or more severe morning sickness implies twins or multiple babies. However, the evidence behind this is unclear and it is more anecdotal.

What does it mean if I don't have morning sickness?

If you don't have morning sickness, don't worry, it is not a problem and is completely normal. We believe morning sickness occurs due to the large quantities of hormones produced during pregnancy but other factors such as "low blood sugar, increased stomach acid, stress and fatigue can also contribute" explain Pampers.

Some women may suffer from nausea but no vomiting or no symptoms at all. If you avoid all morning sickness and nausea, count yourself lucky. At least you have dodged one of the many less than pleasant pregnancy side effects.
