👉 Pregnancy math involves calculating the estimated due date (EDD) based on the last menstrual period (LMP), which is crucial for prenatal care and planning. The EDD is determined by adding the number of weeks from the LMP to the first day of the next expected menstrual period. However, this calculation can vary depending on factors such as menstrual cycle length, ovulation timing, and the presence of fertility treatments. For example, if a woman has an irregular cycle and ovulates 2 weeks before her LMP, the EDD might be 28-32 weeks from the LMP. More precise methods, like ultrasound or hormonal tests, can refine these estimates, but pregnancy math provides a foundational understanding for healthcare providers and expectant parents.
