Sick of taking the pill every day?Try fertility awareness!

Think your choices are limited to taking the pill or using condoms? Well, now there’s an effective means of contraception that doesn’t require filling your body with unnecessary hormones and suffering the adverse emotional and physical consequences. Additionally, you no longer need to be concerned about the reduced sensitivity that condoms bring. The Valley Electronics Pearly is a natural solution to all of your contraceptive woes. By determining the times at which you are most fertile, it enables you to ascertain when it is safe to have sex without conceiving.

Don’t be worried sick about contraception!

What is Pearly?

This really is the most valuable pearl you will ever own! The Valley Electronics Pearly offers contraception and birth control without any unwanted side effects or recurrent costs. Featuring an easy to read LCD display, and a simple oral thermometer, it records your basal temperature each morning, determining the times at which you are most fertile.

Cleverly programmed with natural family planning research, it has a database of more than 900,000 different women’s cycles stored. Using bio-mathematical forecasting calculations, as well as the very latest computer techniques, it adjusts to your individual cycle and ovulation, predicting the times at which you are most fertile.

pEARLYThe Valley Electronics Pearly is proven to be an extremely effective method of contraception. In fact, clinical studies report it to be 99.3% accurate as an ovulation calculator. Differing from other products on the market, it leaves a 5 day window for possible fertility. This is because sperm can survive in a woman’s body for up to this length of time.

It’s something you just can’t do without.

Please note: medications that affect your basal body temperature can reduce the accuracy of the readings.

What does Pearly provide for me?

Pearly is not just a one trick pony. In addition to being an effective means of contraception, it is also a fabulous fertility calculator and pregnancy indicator. It features an LCD display with time, date, year, time zone, shift work and an alarm clock. Once you have mapped your cycle, it will display fertility, ovulation day, cycle day, 99 previous day readings and 6 days’ future predictions.

There are three coloured lights on the Pearly: red meaning fertile or ovulating, amber meaning Pearly is still learning your cycle or regular readings have been missed, and green meaning infertile (safe to use as natural contraception). The product has an 8-10 year life expectancy and measures 7 cm x 10 cm.

Pearly provides all the protection against pregnancy that you need.


When it comes to sex, do condoms mean that you’re just not ‘feeling it’ lately? Well, we’re all aware of the two most common methods of contraception, but all too often we fail to realise that there are other options available to us. Many times, it’s a case of opting for the lesser of two evils; either put chemicals in our bodies and endure the side effects (including headaches, nausea, mood swings), or tolerate that reduced sensitivity that condoms are so well known for. And did you know that neither of these methods are 100% successful anyway? In fact, condoms have a particularly high failure rate, at 18%[1].

Many women opt for hormones as their preferred method of contraception. Scarily, this has the potential to affect fertility in the long run. In terms of the pill, it can take years for a woman’s cycle to return to normal after they stop taking it. In addition, it can be an unreliable method where it is not taken at the same time daily, and a number of medications can render it useless. It’s believed that for every year the pill is taken, the cervix ages by an extra year[2] and taking for a prolonged period of time can increase the risk of cervical or breast cancer[3].

The Valley Electronics Pearly enables you to enjoy a natural form of contraception, without putting your health at risk. It can be used alongside other contraceptive methods that are not hormone based or invasive. But please remember, the Pearly is designed for those in a monogamous relationship; fertility awareness can be an effective means of natural birth control, but does not protect against sexually transmitted infections.

Pearly won’t let you down.

Daily obstacles

Each day brings with it its own challenges. So why not let Pearly do some of the hard work for you?

Many distractions can prevent you from tracking your own cycle, and there is no method of doing so that is 100% reliable. The Pearly can help. Even if the battery goes flat, this clever device will store all of your data and the internal clock will keep counting, ready for when it comes back on. The data is also incredibly difficult to delete and, as such, it cannot be done by mistake, even if those little terrors get their hands on it, or you accidentally press the wrong buttons.

although drinking, lack of sleep, or illness shouldn’t affect Pearly’s performance; the fertility indicator may appear due to a high temperature. As such, it is recommended that you stop using until you are 100% again. Omitting the odd reading here and there won’t affect the reliability of the data; Pearly will generate missing data over short periods and still continue as normal. However, it is best to keep a regular diary.

Take each day as it comes with Pearly.

When do I use Pearly?

As women, we’re used to making plans around our time of the month. No-one wants to organise a romantic weekend away, only to have an unwelcome and unwanted surprise sprung upon us. However, now that romantic weekend away can be even better. Forget worrying about contraception, Pearly is small and discreet, so it is the perfect accompaniment, even on those naughty weekends away. Now you can have the time of your life without any of the worry whatsoever!

It is possible to start tracking our cycle from the age of 19, as this is typically when it becomes regular. However, you can do so at any age thereafter. After giving birth, you are physiologically infertile for approximately 6 weeks. In this instance, we recommend that you don’t start using your Pearly until after this time. Unfortunately, it cannot predict your first ovulation, it will, however, confirm it. Following this cycle, Pearly will be able to predict fertility as normal.

Accurate to 1/100 degrees, it takes merely 30 seconds and the push of a button for the oral thermometer to take your basal body temperature and provide a precise reading. It is important that this is done when you wake up, at the same time each day. However, the innovative Chip III generation of Pearly gives women a 6 hour window in which to take their temperature, as long as they have slept prior to doing so. It is therefore ideal for women caring for children, or that work shifts and sleep and different hours during a week. You could take your temperature at 7am on Monday, and at 2pm on Tuesday and Pearly will still be able to formulate a reliable and customised reading.

Pearly is ready when you are.
