Interactive Tool: What Is Your Due Date?

What does this tool help you learn?

This interactive tool calculates your pregnancy due date, an estimate of when you are likely to deliver your baby.

To find your due date, the calculator takes the first day of your last menstrual period (LMP) and adds 40 weeks. If you are planning a pregnancy, you can use this calculator to plan the birth for a certain month or season.

What does your due date tell you?

Your due date is an estimate of when you will likely have your baby, based on the normal length of a full-term pregnancy. Most women deliver within 14 days of their due date.

What's next?

Your health professional will also measure the size of your uterus and use ultrasound testing to determine your due date. For more information on planning a healthy pregnancy, see the topic Pregnancy.

COVID-19 Alert!

Update: Starting the week of 4/27, we will begin offering a few additional GYN appointments in the afternoons. In May, our mammogram department will open for staggered appointments, and we will then begin to have more GYN appointments available. We will still continue to make every effort to keep our waiting room as empty as possible and allow plenty of time between patients. 

To ensure our patients are taken care of, we remain open, just in a limited capacity. However, if you are experiencing flu-like symptoms, or fever with cough or shortness of breath, please call our office to reschedule your appointment at (404) 355-0320. You may also contact our office for any questions.

To minimize the amount of people in the office, please come to your appointments alone. We apologize for any inconvenience, but we are happy to Facetime your loved ones!

For our pregnant patients who are anticipating a visit to the hospital soon, we ask that you limit visitors to just 1 healthy visitor per patient for Labor & Delivery, Antepartum, and Postpartum rooms.  This is to protect you, your baby, and your family/visitor.

We appreciate your understanding.
