A Pregnancy Calculator is a helpful tool for expecting parents to estimate their baby's due date based on the date of the last menstrual period (LMP). It provides valuable insights into pregnancy milestones and helps with planning for the upcoming months.
By entering the first day of your last menstrual period, the Pregnancy Calculator estimates the expected due date using a standard gestation period of approximately 280 days (40 weeks). It also provides information about key pregnancy stages.
