Take control of your body with this simple and highly accurate basic fertility monitor. Lady-Comp fertility monitors track your body temperature and menstrual cycle to give you highly accurate data on your fertility status. This means you can plan for sexual activity to avoid or enhance chances of conception, with reliable results. The Lady-Comp works very simply with the attached thermometer, which you place under your tongue each morning to take your temperature (a convenient built-in alarm ensures you don’t forget). Quickly check your current fertility status as needed, and you’re set. This Lady-Comp Basic is an ideal starter for natural fertility monitoring, and the software can be easily upgraded to the full Lady-Comp or Lady-Comp Baby functions without having to invest in a new monitor. The Basic is powered by 3 AAA batteries, and can be USB synched to your computer to download and save your data. It’s lightweight at 130g, and the 9cm diameter unit is easily tucked into your bag so you’ll always have it handy.
