Pregnancy Term & Due Date ๐Ÿคฐ

Pregnancy is a term used to describe a woman's state over a time period (~9 months) during which one or more offspring develops inside of a woman. Childbirth usually occurs approximately 38 weeks after conception, or about 40 weeks after the last menstrual period. The World Health Organization defines a normal pregnancy term to last between 37 and 42 weeks. During a person's first OB-GYN visit, the doctor will usually provide an estimated date (based on a sonogram) at which the child will be born, or due date. Alternatively, the due date can also be estimated based on a person's last menstrual period.

Frequently Asked Questions โ“

How accurate are due dates? โฑ๏ธ

Due dates are estimates - only about 5% of women deliver on their exact due date. Most births occur within two weeks before or after the estimated date.

Can my due date change? ๐Ÿ“…

Yes, especially if early ultrasound measurements differ significantly from last menstrual period calculations. Your provider may adjust your due date based on ultrasound findings.

What if I don't know my last period date? ๐Ÿค”

An early ultrasound (6-9 weeks) can provide the most accurate dating. Without this, providers may estimate based on physical exam and other factors.

How is IVF pregnancy dating different? ๐Ÿงช

IVF pregnancies use the embryo transfer date plus 14 days (for Day 5 transfers) to calculate the equivalent of the last menstrual period date.

When should I contact my doctor? ๐Ÿฅ

Contact your provider if you have bleeding, severe pain, decreased fetal movement after 28 weeks, or any concerns about your pregnancy.
