Calculating Estimated Due Date

March 12, 2024

Are you pregnant but you’re not sure exactly when you conceived?

Trying to figure out exactly how far along you are unfortunately is not as easy as plugging in the start date of your LMP (last menstrual period). Most people don’t have an exact 28-day cycle which most calculators are built on. Unless you know the exact day you had sex and you have a very predictable cycle, the date can be off by as much as a week.


The best way to find out how many weeks pregnant you are is through a limited ultrasound. It’s quick and easy and will give you the information you need before your next step.


To schedule a complimentary limited ultrasound, you first need to have a positive pregnancy test at one of our Hope Pregnancy Centers. Your limited ultrasound will be provided by a nurse trained in sonography who can answer your pregnancy questions.
