The expected date of delivery in pregnancy, often called the EDD or due date, is an estimate of when your baby will arrive. While it's exciting to have a specific date in mind, it's important to remember that only a small percentage of babies are born exactly on their due date. Think of it as a target, not a deadline!

Calculate Your Due Date Now! →How is Your Due Date Calculated?
Several methods exist to calculate your due date. Here's a breakdown:
- Last Menstrual Period (LMP): This is the most common method. It involves counting 40 weeks (280 days) from the first day of your last normal menstrual period.
- Conception Date: If you know your conception date (e.g., through ovulation tracking or irregular period conception calculator), add 266 days.
- IVF Transfer Date: For pregnancies conceived via in vitro fertilization (IVF), the due date is calculated based on the embryo transfer date. Day 3 transfers require adding 263 days, while Day 5 transfers need 261 days.
- Ultrasound: An early ultrasound (typically in the first trimester) can provide a more accurate estimation, especially if your periods are irregular.
Keep in mind that an ultrasound may change your due date.

What If My Due Date Changes?
It's not uncommon for healthcare providers to adjust your due date based on ultrasound findings, particularly if there's a significant discrepancy between the LMP-based date and the baby's size. Factors like irregular periods can affect initial calculations.Don't be alarmed; it simply means your healthcare team is refining the estimate for the most accurate prediction!
Remember the Range
It's also important to keep in mind that your due date is just an estimate. Most pregnancies spontaneously start between 37-42 weeks. Full-term is considered 39 weeks and 0 days, to 40 weeks and 6 days
