The estimated due date (EDD) is a significant milestone in every pregnancy, marking the approximate time when you can expect to welcome your baby into the world. While it's an exciting point to anticipate, it's essential to understand what a due date represents and how it's calculated. This guide explores the various facets of "due date delivery pregnancy," providing insights to help you navigate this period with confidence.

Calculate Your Due Date Now →How is a Due Date Calculated?
Several methods are used to calculate your due date, each with its degree of accuracy:
- Last Menstrual Period (LMP): The most common method involves counting 280 days (40 weeks) from the first day of your last menstrual period. This method assumes a 28-day cycle and ovulation occurring on day 14.
- Conception Date: If you know the exact date of conception, adding 266 days provides a more precise estimate.
- IVF Transfer Date: For pregnancies achieved through in vitro fertilization (IVF), the embryo transfer date offers a reliable starting point. The calculation varies slightly depending on whether a 3-day or 5-day embryo was transferred.
- Ultrasound: An early ultrasound, ideally performed in the first trimester, can accurately determine gestational age based on the baby's development.
Our Pregnancy Calculator simplifies this process, allowing you to input your LMP, conception date, or IVF transfer date to get your estimated due date, track key milestones, and understand your current trimester.
Factors Affecting the Accuracy of a Due Date
While due dates offer a helpful timeline, several factors can influence their accuracy:
- Irregular Cycles: Women with irregular menstrual cycles may find LMP-based calculations less precise.
- Ovulation Timing: Since conception relies on ovulation, variations in ovulation timing can shift the EDD.
- Individual Baby's Development: Each baby grows at their own pace, so using an ultrasound in the late stages of pregnancy may not be the best way to update the due date since development can vary more significantly between babies at this stage.
Navigating Late-Term Pregnancy and Delivery
A full-term pregnancy is considered to be between 39 weeks and 40 weeks and 6 days. Pregnancies extending beyond 40 weeks, are considered late term and those beyond 42 weeks are considered post-term. Here's what to consider during this time:
- Increased Monitoring: As you approach or pass your due date, healthcare providers may recommend increased monitoring to assess the baby's well-being and placental function.
- Membrane Sweep: A membrane sweep can be offered to stimulate labor naturally between 39-41 weeks.
- Induction of Labor: Induction may be recommended if pregnancy extends significantly beyond the due date, typically after 41 weeks, to mitigate potential risks.

Frequently Asked Questions
- Can my due date change? Your doctor may adjust your due date based on early ultrasound findings or other medical considerations.
- What if I have irregular periods? Our calculator can use your average cycle length for a more accurate estimate, but an ultrasound is still the gold standard!
- Is a due date a guarantee? No, it's an estimate. Only a small percentage of babies are born exactly on their due date.
