How many days are in 4 weeks of pregnancy?

How to calculate the number of days of pregnancy

From this time on, adding 266 days is a more accurate delivery date.

However, since most people cannot determine the insemination day, because the day of intercourse is not necessarily the insemination day, and the previous calculation method is also relatively convenient, although this 280 time includes life without pregnancy, these are all normal. The most common and general way of calculating is to count backwards from 280 days (40 weeks of pregnancy), and then add 9 (or subtract 3) to the day of the last menstrual period.
