The first day of a lady’s last menstrual period was 15 Sep 2019. What is the estimated date of delivery?

Correct option is C

1. Start with the first day of the last menstrual period (LMP): 15 Sep 2019.
2. Add one year to the year of the LMP:
   15 Sep 2019 → 15 Sep 2020.
3. Subtract three months from the month of the LMP:
   September → June.
4. Add seven days to the date:
   15 June 2020 + 7 days = 22 June 2020.

Estimated Date of Delivery (EDD):

• The EDD is June 22, 2020.
