Calculating Your Conception Date

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 of finding out how many weeks you are is through a diagnostic ultrasound. It’s quick and easy and will give you the exact information you need before your next step.

You can make your appointment for a complimentary ultrasound and speak to a nurse today.
