Last menstrual period date:
Pregnancy is an amazing time in a woman’s life. There’s so much to think about and prepare for! If you are a to-be Mother, your biggest question is When is my Baby Due? Although due dates aren’t very accurate, they’re still used as a baseline for when to expect your little one.
How do Pregnancy Dates are Calculated?
Most people are born within a week of their due date. However, a pregnancy is considered full-term at 37 weeks, so a baby delivered 2-weeks before its due date is still considered premature. Due dates are calculated by counting forward from the first day of your last period. That means if your last period started on April 15, you’d be due on January 22.
If you know the date of conception, the day sperm fertilizes an egg; you can count 38 days to determine a due date. A blood test and ultrasound can also be used to more accurately predict a due date, especially when the date of the last period is unknown.
