About Pearly – NFP Monitor Quality with Budget Solution

The Pearly fertility computer operates with the same advanced technology as the Lady-Comp Natural Family Planning computer (for more about these features go to: ‘Lady-Comp’) but is designed for convenience in a pocket sized model.

The Pearly is an affordable alternative, however, it does have a few less features then the Lady-Comp. Please see ‘Pearly’ / ‘Lady-Comp’ Comparison Chart’ below.

‘Pearly’ Monitor perfectly supports your natural family planning goals

‘Pearly’ Monitor is very easy to use. 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 menstrual cycle data.
It monitors your daily status of fertility and will inform you on the days when you can get pregnant,
on the day you ovulate – and the five days before ovulation.

No hormones: No side effects

There are six days in every cycle when a woman can get pregnant: five days before ovulation and on the day she ovulates. You don’t have to use pills or coil, which are not only invasive but also act in anti-implementation way for an embryo when breakthrough ovulation happens (third mechanism of the pill and coil) – if you would like to know more about all side effects (cancer, infertility, health complications) of hormonal pills and intrauterine device (IUD) and why they also act in anti-implantation way, please go here.
You don’t have to suppress your normal body functions to be yourself.

Better every time

In the beginning, you should take your wake-up temperature as regularly as possible because the more information the computer collects, the easier it is to narrow down the number of fertile (red) days. The computer is safe from the first measurement on. The more data you give the computer the more the computer knows about you.

99.3 percent effective – clinically proven reliability

The fertility computer takes your basal body temperature (BBT) every morning when you wake up with the most advanced temperature sensor (1/100 degrees accurate). It then automatically compares it with its bio-mathematical forecasting software and stored information of all available family planning research. It also automatically compares it to hundreds of thousands of cycles of other women to accurately determine, analyze and display your individual cycle. This is why the intelligent fertility computer is one of the most effective fertility monitors in the world. It is 99.3% effective right from the start. A Pearl Index of 0.7 means that this 100-percent natural method is 99.3 percent safe and effective.

‘Pearly’ vs ‘Lady-Comp’ – Compare

The Pearly fertility computer operates with a lithium battery that must be replaced by the distributor every 2-3 years in order to safely restore your historical basal body temperature readings to the device. The cost of a battery change is 35.00 Euro plus shipping and this includes a Free Clinical Printout.

The Lady-Comp operates with an integrated rechargeable battery and is also equipped with a power supply adaptor. No battery changes are required.

The Pearly is equipped with a thermal sensor that cannot be replaced if damaged. The Lady-Comp is equipped with a thermal sensor that can easily be replaced at a minimal cost should this be necessary.
