How does our due date calculator work?

Our due date calculator is easy to use. Simply enter the first day of your last menstrual period and the length of your menstrual cycle, and the calculator will estimate your due date.

It's important to note that this is just an estimate and your due date may change based on the results of your ultrasound or other factors. Your healthcare provider will be able to provide you with a more accurate due date based on your individual circumstances.

How is your due date determined?

Your due date is typically determined by counting 40 weeks (280 days) from the first day of your last menstrual period. However, this method assumes that you have a regular menstrual cycle and ovulate on day 14 of your cycle. If you have irregular periods or ovulate at a different time in your cycle, your due date may be different.

Your healthcare provider may also use an ultrasound to determine your due date. This method measures the size of the fetus and can provide a more accurate estimate of your due date.

What can you expect during pregnancy?

Pregnancy is a unique experience for every woman, but there are some common experiences and milestones that you can expect. Some of these include:

  • Nausea and vomiting (morning sickness) in the first trimester
  • Weight gain
  • Fatigue
  • Swollen and tender breasts
  • Increased urination
  • Fetal movements in the second and third trimesters
  • Braxton Hicks contractions (practice contractions)
  • Preparing for labor and delivery

It's important to maintain regular prenatal care with your healthcare provider throughout your pregnancy to monitor your health and the health of your baby.
