132 views

Determining the exact week you got pregnant can be challenging due to natural variations in menstrual cycle length and the time of ovulation. However, healthcare providers commonly use the first day of your last menstrual period (LMP) to estimate your due date and pregnancy timeline, including conception week. For a more precise estimate, ultrasound scans early in pregnancy can provide a clearer picture of gestational age. Consider tracking your cycles and discussing your history with a healthcare provider for the best estimate.

  2. How do doctors estimate my pregnancy due date? Doctors typically use the first day of your last menstrual period (LMP) and early ultrasound measurements to calculate your estimated due date and gestational age.
  3. Why is ultrasound used to date a pregnancy? Ultrasound provides a more precise measurement of fetal development and gestational age early in pregnancy, helping refine due date estimates beyond menstrual cycle assumptions.
