The journey to pregnancy begins with understanding your menstrual cycle and pinpointing ovulation. Ovulation is when your ovary releases a mature egg, ready for fertilization. This fertile window, typically lasting about six days, includes the five days leading up to ovulation and the day of ovulation itself.

Estimate Your Due Date & Track Ovulation →Knowing your https://pregnancy-calculator.org/blog/ovulation-symptoms can help you plan for conception, but how does this relate to your estimated due date (EDD)?
Calculating Your Due Date: Methods & Considerations
Several methods exist for estimating your due date, each with its own level of accuracy. Here’s a breakdown:
- Last Menstrual Period (LMP): The most common method adds 280 days (40 weeks) to the first day of your last menstrual period. This assumes a regular 28-day cycle, with ovulation occurring around day 14.
- Conception Date: If you know your exact conception date (e.g., through ovulation tracking or IVF), adding 266 days (38 weeks) provides a more precise estimate.
- Ultrasound: An ultrasound, particularly in the first trimester, offers the most accurate dating by measuring the size of the fetus.
The Role of Ovulation in Determining Your Due Date
While the LMP method is widely used, it's important to acknowledge that not all women have perfectly regular cycles. If your cycle is shorter or longer than 28 days, using your https://pregnancy-calculator.org/ovulation-calculator to determine your ovulation date can lead to a more personalized and accurate EDD when compared to the LMP calculation.
Factors That Can Affect Your Due Date
Keep in mind that your initial due date is an estimate, and several factors can influence its accuracy:
- Irregular Cycles: Irregular menstrual cycles can make it difficult to pinpoint ovulation, impacting the accuracy of LMP-based calculations.
- Late or Early Ovulation: Ovulating earlier or later in your cycle than the typical day 14 can shift your EDD.
- Ultrasound Findings: Discrepancies between the LMP-based EDD and ultrasound measurements may prompt your healthcare provider to adjust your due date.
