Finally a Pregnancy Due Date Calculator That You Can Adjust to Your Menstration Cycle

Unlike many of other calculators this calculator will give you a chance to adjust your due date calculation to your own period cycle.

For example if you period is on 28 or 32 day cycle you can get a more accurate due date projection.

You have probably seen due date calenders all over the web and all of them are based on a simple formula.

How your pregnancy due date is calculated:

Your due date is estimated by adding 40 weeks (280 days) to the approximate first day of your last menstrual period.

Well to find out what your estimated due date is:

• Enter the first day of your most recent menstrual cycle below

• Option 1 enter menstral cycle length

• Option 2 enter luteal phase*

* (The luteal phase, or post-ovulation (from ovulation to menstruation), is generally the same length for most women - averaging about 14 days)

and you will be able to follow your baby's development by using the information provided by PWSH throughout your pregnancy.
