Determining your Estimated Gestational Age (EGA) is a crucial step in understanding and tracking your pregnancy. One common method for calculating EGA is by using the date of your Last Menstrual Period (LMP). This approach provides an initial estimate that can be further refined through ultrasound and other medical assessments.

Using your LMP to calculate your EGA offers several benefits:
- Early Estimation: It provides an immediate estimate of your pregnancy timeline, even before an ultrasound appointment.
- Tracking Milestones: Knowing your EGA helps you understand which developmental milestones your baby is expected to reach at different stages of the pregnancy.
- Informed Planning: It allows you to better plan for prenatal care, screenings, and other important appointments throughout your pregnancy.
How the Pregnancy Calculator & Ovulation Estimator Can Help
Our Pregnancy Calculator & Ovulation Estimator offers a seamless way to determine your EGA using your LMP. This tool goes beyond a simple calculation by also allowing you to:

Factors Affecting EGA Accuracy
It's important to acknowledge factors that might affect the accuracy of an EGA calculation based on LMP:
- Irregular Cycles: Women with irregular menstrual cycles may find that the LMP method provides a less precise estimate.
- Recall Accuracy: The accuracy depends on remembering the correct date of your last period.
- Variations in Ovulation: LMP assumes ovulation occurs 14 days after menstruation starts, but this varies among women.
For a more precise assessment, consult with your healthcare provider for ultrasound confirmation.
Beyond the Calculator: Comprehensive Reproductive Health Planning
While an EGA calculator by LMP is a great starting point, remember that reproductive health planning includes more than just tracking pregnancy. Our tool also allows you to:
- Pinpoint your fertile window for conception using the ovulation estimator.
