pregnancy due date

The pregnancy due date calculator is based on the concept that generally the pregnancies last around 38 weeks from conception. Further, the calculator provides week by week position during pregnancy. This pregnancy due date calculator will provide a rough idea of when your baby should be born. If you know the date of the first day of your last menstrual period (LMP), or have already had your first ultrasound scan, you can use this calculator.

Note that this table assumes a 40-week gestation period, which is the standard length of a full-term pregnancy. However, it’s important to keep in mind that due dates are estimates and that only about 5% of women actually deliver on their due date. Additionally, due dates can be affected by various factors, such as irregular menstrual cycles and variations in fetal growth, so it’s always a good idea to discuss any concerns or questions with a healthcare provider.
