The Lady-Comp family of fertility monitors supports your natural family planning goals like no other.


Monitor your menstrual cycle.



There are six days in every cycle when a woman can get pregnant: five days before ovulation and on the day she ovulates. However, the timing of ovulation can vary from cycle to cycle.

Lady-Comp is an intelligent fertility monitor — a next-generation computer that learns, analyzes, and indicates fertile and infertile days.


Why choose Lady-Comp ovulation calculators?

Every Lady-Comp is programmed with decades worth of natural family planning research data, contains a database of more than five million cycles, and uses bio-mathematical forecasting calculations, as well as the very latest computer programming. It is a personal fertility monitor which learns and adjusts to your individual cycle, accommodating most cycle irregularities and varying cycle lengths. Lady-Comp is a one-time purchase without any recurring costs. 



Wake up - Measure - Done:

Lady-Comp makes tracking your cycle easy. Based on your morning temperature, taken orally, the fertility computer determines your fertile days and shows when you are ovulating by recording, analyzing, and storing your temperature and menstrual cycle data. It monitors your daily status of fertility and will alert you with a red, yellow, or green indicator.


As easy as 1, 2, 3!

  1. Take your temperature each morning.
  2. Enter M on the days you are menstruating.
  3. View your fertility for the day.


The Program

The ovulation computers are programmed to accurately determine and display the time of ovulation in the female body. Ovulation causes a slight, but noticeable, rise in body temperature. When you measure your temperature with the sensor every morning before you get up, the fertility computer evaluates the data and quickly recognizes your individual fertility pattern.

If you are potentially fertile, the computer will display a red light. If you are infertile, the computer will show you a green light. If the device needs more information, the computer will show you a yellow light.
