How is my due date calculated?

Your due date is calculated by adding 280 days (40 weeks) to the first day of your last menstrual period (assuming a 28-day cycle).

Note that your menstrual period and ovulation are counted as the first two weeks of pregnancy. If you deliver on your due date, your baby is actually only 38 weeks old, not 40.

Is there a backend or settings page?

Settings page coming soon.

Added the shortcode. On frontend I put in the required dates but when I submit it takes me back to my homepage. No other clear instructions on using the plugin!

Nice Style - Due Date Calculation Bug

By danney07 on July 26, 2022

The Due date (birthing date) must be in past ... but of course normally the due date is in future. The plugin forces me to enter a due date which is not later than TODAY and then tells me, that I am in week 40. 5 Star rating after fixing the bug.
