The earliest symptoms of pregnancy include menopause, nausea, vomiting and loss of appetite.
As the level of progesterone in a woman’s body gradually increases after pregnancy, the endometrium grows and thickens under the action of progesterone, which can play a role in protecting the embryo and improving nutrition for the embryo, and the endometrium will not undergo a cycle of shedding and bleeding, and will not have a menstrual period, so the earliest reaction to pregnancy is menopause.
When a woman is pregnant, the increased level of human chorionic gonadotropin in her body will easily affect the secretion of gastric acid and reduce the activity of digestive enzymes, resulting in gastrointestinal disorders, nausea, vomiting, loss of appetite and other early pregnancy reactions.
If women experience the above pregnancy reactions, it is recommended that they go to the hospital for human chorionic gonadotropin test to clarify whether they are caused by pregnancy.
