WP Pregnancy & Ovulation Calculator

For health, parenting & family planning websites: the most complete pregnancy and ovulation calculator plugin for WordPress! WP Pregnancy & Ovulation Calculator by Belov is a plugin and a marketing tool that helps you engage visitors on health and family planning websites. This plugin turns your WordPress site into a helpful resource for expectant parents and couples planning a family. Whether you run a parenting blog, a women's health clinic website, or a fertility support platform, the WP Pregnancy & Ovulation Calculator will keep your visitors coming back. Having a pregnancy or ovulation calculator on your website is an absolute must if your business is in the maternal health, parenting, or family planning space. Your visitors will love the opportunity to track due dates, pregnancy milestones, and fertile windows right on your site. Make your service stand out and get more leads! FIVE PREGNANCY CALCULATION METHODS No two pregnancies are the same, and neither should your calculator be. WP Pregnancy & Ovulation Calculator offers five distinct methods to ensure every visitor gets the most accurate results:

• Due Date Calculator — Estimate the due date based on the last menstrual period
• Last Period Calculator — Calculate the last period date from an estimated due date
• Conception Date Calculator — Find out the conception date and other key pregnancy milestones
• Ultrasound Due Date Calculator — Determine due dates using ultrasound measurements
• IVF Pregnancy Calculator — Special calculations for pregnancies conceived via IVF

OVULATION & FERTILITY TRACKING Help your visitors plan ahead with precise ovulation and fertility window calculations. The ovulation calendar displays fertile days, ovulation dates, and the best times to conceive — all based on scientifically recognized cycle-length formulas. SCIENCE BEHIND THE CALCULATIONS Pregnancy tracking involves many variables — last menstrual period, cycle length, ultrasound data, and more. Doing those calculations manually is impractical and error-prone. Our calculator uses Naegele's rule and other standard obstetric formulas trusted by healthcare professionals worldwide. The results include estimated due dates, trimester breakdowns, and week-by-week pregnancy milestones — giving your visitors a comprehensive view of their pregnancy journey. HOW IT WORKS WP Pregnancy & Ovulation Calculator gives you a shortcode to place on any page, post, or widget. Put it where it catches the most attention! Dates, methods, milestones: the calculator covers everything Once installed, you get an intuitive settings panel in your WordPress admin area. Configure the calculation method, date formats, result display, and styling — all in one place. Generate your shortcode and paste it anywhere on your site. Flexible date formats The plugin supports multiple date formats (MM/DD/YYYY, DD/MM/YYYY, and more) to suit your audience worldwide. No confusion, no manual conversion needed. Increasing screentime A pregnancy calculator is one of the most engaging features you can offer. Expectant parents can't resist checking their due dates, tracking week-by-week progress, and exploring fertility windows. Keep them on your site longer! Handy & user-friendly The calculator displays results instantly after submission — clear, visual, and beautifully formatted.
