Most of you will not feel anything in the first few days of pregnancy, but if you are more sensitive, you may experience breast swelling and a slight feeling of cramping in the lower abdomen. Normally, the reactions that occur in early pregnancy are closely related to the level of hormones in the body. Generally, the secretion of human chorionic gonadotropin starts on the 6th day after conception, the trophoblast cells start to secrete hormones and the progesterone gradually increases. If the embryo is well developed, human chorionic gonadotropin can double every other day. Around 40 days after menopause, pregnant women will experience dizziness and weakness, nausea, vomiting, and anorexia for oil. During the first days of conception, the hormones are not yet secreted, so the symptoms are usually not obvious. During this period, patients are advised to relax and avoid bad emotions such as tension and anxiety, and there is no need to over-experience their feelings to prevent misjudgment. If menopause occurs, prompt examination should be performed to clarify whether pregnancy is present.
