## About

Premom Ovulation Calculator helps users estimate an ovulation day, fertile window, next period, and when to begin LH ovulation test strips from the first day of the last period and average cycle length. It opens an interactive educational calculator in ChatGPT and supports English, German, and Simplified Chinese. The app does not connect to a Premom account, sell products, or direct users to an external website. Results are cycle-based educational estimates and are not a substitute for professional medical advice.

## How to use

1. **Add it in ChatGPT** Open Premom Ovulation Calculator in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Premom Ovulation Calculator, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Example prompts

- "When is my fertile window if my last period started August 1 and my cycle is 28 days?"
- "When should I start using LH ovulation test strips this cycle?"
- "Estimate my next ovulation day and period from my cycle dates."
