Pregnancy is typically measured from the first day of your last menstrual period (LMP), lasting about 40 weeks. However, conception usually occurs about 2 weeks after the LMP. Our calculator adjusts for these differences to give you the most accurate timeline.
Healthy weight gain depends on your pre-pregnancy BMI. Underweight women may need to gain more, while overweight women may need to gain less. Our tool provides specific ranges based on Institute of Medicine guidelines to support a healthy pregnancy.
Due dates are estimates, not deadlines! Only about 5% of babies are born on their exact due date. Most arrive within a window of two weeks before or after.
