Hello, I would like to ask you how to calculate the expected date of pregnancy after abortion and pr

Pregnant women can take the first day of the last menstrual period as the beginning of pregnancy. Generally, the month of the last menstrual period plus 9 or minus 3 is the number of months due to the expected date; the number of days plus 7 is the expected date. If you are pregnant, you need regular check-ups and pay attention to rest.
