To find out how far pregnant you are, the most common method is to calculate from the first day of your last menstrual period (LMP). Pregnancy typically lasts about 40 weeks (280 days) from that date. By entering the first day of your last period into a pregnancy due date calculator, you can estimate both your due date and how many weeks pregnant you currently are
. Here’s how you can do it:
- Note the first day of your last menstrual period.
- Use an online pregnancy due date calculator or ask your healthcare provider.
- The calculator will count forward 280 days (40 weeks) to estimate your due date.
- It will also tell you how many weeks pregnant you are based on today’s date.
If you know your exact conception date, some calculators can use that to estimate your pregnancy length by counting 266 days from conception
. For the most accurate estimate, a healthcare provider may perform an ultrasound around 12 weeks to confirm how far along you are and adjust your due date if necessary
. If you want, I can guide you through calculating your pregnancy weeks if you provide the date of your last period or conception. Otherwise, you can use any reputable online due date calculator by entering that date.
