For women who are pregnant for the first time, they are not very familiar with pregnancy related matters, such as early pregnancy reactions. Early pregnancy reactions are a very common symptom during pregnancy, but some women have heard of this term for the first time and are not familiar with early pregnancy reactions. So, what is early pregnancy reaction?
Early pregnancy reaction, also known as pregnancy reaction, refers to a series of symptoms that occur in the early stages of pregnancy, usually related to the enlargement of the uterine volume and the continuous increase of HCG in the body after pregnancy. When sperm and egg meet and combine in the ampulla of the fallopian tube, they form a fertilized egg, which takes about a week to implant and develop in the uterine cavity.
After pregnancy, due to significant changes in hormone levels in the body, women may experience a series of early pregnancy reactions, such as nausea and vomiting, fatigue, decreased appetite, breast swelling, etc. Generally, early pregnancy symptoms vary from person to person. Most of them begin in the fifth or sixth week of pregnancy and gradually disappear around the thirteenth week.
Morning sickness is a common reaction in pregnant women. For some women with already weak gastrointestinal function, after pregnancy, due to reduced gastric acid secretion and decreased digestive enzyme activity, the morning sickness reaction will be more pronounced. After pregnancy, women with a heart are more sensitive to their senses and are more sensitive to certain odors. If they smell odors that make them uncomfortable, it can also exacerbate morning sickness and nausea.
