When the sperm and egg unite and develop into a fertilized egg, after transplantation into the uterine cavity, there may be discomfort such as soreness and swelling of the stomach, and falling, etc. A few women have individual differences, but most women have the equivalent of the second half of the menstrual cycle after the sperm-egg union, and women can work, live and study normally without physical discomfort. If a woman’s expectation of pregnancy is high, she can postpone her period for a week or so. If the level of human chorionic gonadotropin in the blood is elevated, a gynecological ultrasound is needed at a later stage to confirm the diagnosis of normal intrauterine pregnancy and to pay attention to proper rest and avoid abnormalities such as cold, flu and exertion.
