"When is the baby due?" It’s usually the very first question everyone asks!
Calculating your Estimated Due Date (EDD) generally comes down to two main methods, as shown in our graphic:
1️⃣ The Last Menstrual Period (LMP) Method: Counting 40 weeks (280 days) from the first day of your last period. This is the standard rule of thumb assuming a typical 28-day cycle.
2️⃣ The Conception Method: If you know the exact day you ovulated (or conceived), counting 38 weeks (266 days) forward from that specific date.
Our Tip: While these calendar methods give us a fantastic starting point, many women have irregular cycles or ovulate a bit earlier or later than day 14. That is why an early dating ultrasound scan (usually between 7–11 weeks) is performed for confirming your official due date.
