Morning sickness is one of the more common symptoms of pregnancy. It is often the first symptom women notice before they find out they are pregnant. So when does morning sickness start, and why does it happen?
Morning sickness affects more than 60% of pregnant women. For some women, it only affects them in the morning. For a lot of women, morning sickness occurs more than just the morning. I think that more often than not, it should be called All Day Sickness.
I had morning sickness with both of my pregnancies. Nausea would be terrible most of the morning, then again in the evening well into the night. There would be a brief window in the afternoon when I would feel okay.

What is Morning Sickness?
Morning Sickness refers to nausea and vomiting that occurs early in pregnancy. Despite the name, it is not something that happens only in the morning. It can affect you at any time.
It will usually ease up at the start of your second trimester. 10% of pregnant women end up having morning sickness throughout their whole pregnancy.
The main cause of morning sickness is relatively unknown. But, it has been linked to the change in hormones during early pregnancy.
Hormone changes during pregnancy
There is a rapid increase in estrogen during the first trimester of pregnancy. Estrogen makes it possible for the formation of the placenta. Estrogen improves vascularization and allows nutrients to be transferred to support the growing baby.
There is also an increase in progesterone. One of the things that progesterone is responsible for is the increase in the size of the uterus. Progesterone relaxes smooth muscle and loosens ligaments and joints throughout the body. This allows the uterus to accommodate a growing baby.
The rapid increase in hormones can be the cause of a lot of nausea during the first trimester. Doctors consider morning sickness a good sign in pregnancy. It means that the body is creating the necessary hormones required for a healthy pregnancy.
When does morning sickness start?
Morning sickness starts around 5-6 weeks after conception. Morning sickness is one of the first early signs of pregnancy that is not confused with PMS symptoms, so it is sometimes the first indicator that they are pregnant.

Morning sickness will usually last until week 12-14 of pregnancy. Once the second trimester begins, many women feel a lot better. Their energy picks up, and their appetite is back as well. Once you feel like eating again, make sure you are including these Superfoods in your pregnancy diet.
If nausea and vomiting become severe, it may be a condition called hyperemesis gravidarum. It is a severe morning sickness case that can lead to dehydration and electrolyte imbalances that can be harmful to your baby. If you are experiencing severe symptoms, be sure to see a doctor right away.
