I went for an ultrasound and was 7 weeks and 5 days pregnant. The ultrasound doctor said the fetus was healthy. And before that, I had a lot of morning sickness and vomited a lot during the day. The week before, September 8, 2021, I weighed 47kg and on September 15, I weighed more than 45kg. Doctor, can you tell me if it is normal for morning sickness to suddenly stop during pregnancy?

Sleep plays an important role in human circadian rhythm. During pregnancy, most pregnant women suffer from sleep disorders, of which over 90% of pregnant women suffer from insomnia.

Morning sickness during pregnancy usually occurs from the 5th to 18th week of pregnancy. According to statistics, about 50 - 90% of women experience nausea during pregnancy, with or without vomiting. The severity and duration of nausea during pregnancy symptoms vary from woman to woman.
