Even if the sperm and egg have united to form a fertilized egg after intercourse, there will be no corresponding early pregnancy reaction if there is no history of menopause. If you are pregnant, most of you will experience clinical symptoms about 40 days after menopause, such as nausea, anorexia, hypersalivation, or vomiting, as well as localized swelling and pain in the breasts, enlargement of the breasts, and coloring of the nipples and areolas, which are the early pregnancy reactions. Due to individual differences, the time of early pregnancy reaction will also be different, some people are relatively sensitive and have early pregnancy reaction, while others have late pregnancy reaction, which is normal. It is recommended to use morning urine to do early pregnancy test when there is a history of menopause, for example, after 35 days of menopause.
