WordPress Pregnancy Calculator 2.4

A **WordPress Pregnancy Calculator** is a valuable interactive tool for parenting blogs, health clinics, and wellness websites. It allows visitors to estimate their due date, conception date, and current trimester milestones based on their Last Menstrual Period (LMP) or conception date. 

In 2026, there are three primary ways to add this functionality to your site: 

--- 

### 1. Dedicated Pregnancy Calculator Plugins 

These are "plug-and-play" solutions that offer pre-built formulas and professional designs. 

* **Ultimate Pregnancy & Ovulation Calculator:** One of the most comprehensive options. It supports multiple calculation methods, including **LMP, Ultrasound, Conception Date, and IVF transfer**. It is fully responsive and can be added anywhere via a shortcode. 
* **LMP Pregnancy Calculator (by Coders Time):** A lightweight plugin focused specifically on generating a detailed pregnancy report (estimated due date, fetal age, and key scan date ranges like the Morphology scan). 
* **Smart Pregnancy Calculator:** A simple, free tool that provides estimated due dates. The Pro version often includes advanced features like **PDF result downloads** and lead generation (email capture).

### 2. Multi-Purpose Calculator Form Builders 

If you want total control over the design and the ability to collect user emails, a form builder is the best choice. 

* **Calculated Fields Form:** This is the "gold standard" for custom calculations. It comes with a **pre-made Pregnancy Calculator template** that you can import and customize. You can adjust the math to be as simple or complex as you like. 
* **Formidable Forms:** Known for its "Calculator" templates. It allows you to create high-end calculators that can also save user data to your database, which is great for building a subscriber list of expecting parents.

### 3. External Widget Embeds (Elfsight / CodesMade) 

If you don't want to install a heavy plugin, you can use a third-party widget. 

* **Elfsight Pregnancy Calculator:** A beautifully designed, cloud-based widget. You customize it on their website and then paste a small **HTML/JavaScript snippet** into a "Custom HTML" block on your WordPress site. 
* **Pros:** It doesn't use your server's resources and usually has a more modern, "app-like" UI. 
* **Cons:** Free versions often have a "Powered by" watermark or view limits.
