Expected help: I had my period on July 8th. How many weeks pregnant am I now? When do pregnancy-induced nausea usually start?
Doctor's answer:
Starting from the first day of the last menstrual period, the more accurate calculation of pregnancy duration is based on the first day of the last menstrual period, rather than the day of intercourse. Many people calculate the number of days of pregnancy from the day the sperm and egg combine, but this method is actually incorrect. For example, if the first day of the last menstrual period was March 1st, then by April 10th, the pregnancy duration would be 40 days. From a physiological perspective, this means counting the days from the first day of the last menstrual period up to the present time, which is the pregnancy duration.
