FAQs

How to calculate pregnancy due date?

To calculate your due date, add 280 days (or 40 weeks) to the first day of your last
menstrual period (LMP). This method assumes you have a regular 28-day cycle.
However, this can be tricky if your cycle is irregular, or if you're not sure about the exact
date.

To make things easier, you can skip the math and use the Baby Forest Due Date
Calculator. It’s a simple tool that calculates your due date accurately by entering a few
details. This way, you don’t have to worry about doing the calculations yourself!

When is my due date if I got pregnant today?

If you got pregnant today, your due date would be around 40 weeks from now.
However, it's typically calculated from the first day of your last period, not the day of
conception.

Are due dates 100% accurate?

No, due dates are not 100% accurate. They are an estimate, and most babies are born
within a two-week window before or after the due date.

Can I plan my due date?

You can't plan the exact day your baby will be born, but some people choose to
conceive during certain months to aim for a particular time of year. However, nature
ultimately decides when the baby will arrive.

How many weeks is pregnancy?

A full-term pregnancy is typically 40 weeks, but it can last anywhere from 37 to 42
weeks.

How can I know how far along I am?

You can determine how far along you are by calculating the weeks from the first day of
your last menstrual period or through an early ultrasound scan.

Will my due date change?

Your due date might change after an early ultrasound, which can provide a more
accurate estimate based on the baby's growth. However, most due dates remain
consistent unless there's a significant difference in measurements.
