Do you want a natural way to plan your cycle? Fertility management is easy with Lady Comp

Have you been trying for a baby for a while now and you’re beginning to think something is amiss? Or do you want to take control of your contraception naturally and work with your own body without hormones, drugs and intrusive contraception? Then this unique device is the perfect choice, because it can assist you with both. Want to know how? It’s simple; by naturally tracking your cycle, it indicates the days on which you are the most fertile and likely to conceive.

How you choose to use that information is entirely up to you!

What is Lady-Comp?

A highly effective fertility computer, the Lady-Comp offers an innovative method of contraception, as well as being an excellent family planning aid. Not only will it keep you protected against falling pregnant; if and when you’re ready to try for a baby, it will help to make that happen too. With no side effects or recurring costs, it is a safe and natural alternative to other methods of contraception, or costly and potentially harmful fertility treatments. Featuring an easy to read LCD display and a simple to use oral thermometer, it will quickly and efficiently take your body basal temperature each morning to determine your most fertile days.

Programmed using natural family planning research and with a database of more than 900,000 women’s cycles, it uses bio-mathematical forecasting calculations as well as the very latest computer techniques to adjust to your individual cycle and ovulation, regardless of any irregularities. In fact, clinical studies have shown it to be 99.3% accurate as an ovulation calculator.

So, wouldn’t it be easier to ask, what isn’t it?

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

What does Lady-Comp provide for me?

Lady-Comp will provide you with everything you need, whether planning to start a family or simply trying to prevent yourself from doing so. As a fertility calculator, pregnancy indicator and a natural contraceptive method (through fertility awareness), its clever software ensures that it is highly accurate and provides you with all the information needed for your chosen endeavour. Its easy to read LCD screen displays the time, date, year, time zone and it even has an alarm clock.

Once you have mapped your cycle, Lady-Comp will indicate fertility, ovulation day, cycle day, 180 previous day readings and 6 days’ future predictions. It is also able to show body mass index, number of stored cycles, average cycle length, average temperature increase after ovulation and fluctuation on ovulation day. As a pregnancy test, it can detect probable pregnancy after 15 days, and confirmed pregnancy after 18 days.

Three coloured lights will represent your fertility: red signifies fertile or ovulating, amber means Lady-Comp is still learning your cycle or regular readings have been missed, and green indicates infertile (safe to use as natural contraception).

Lady-Comp has a 10 year life expectancy.


menstrual cycle diagramSick of those terrible mood swings that you get from taking the pill? Or do condoms mean that neither of you are really ‘feeling it’ lately? Well, all too often, we think that our options are limited to one of these, or, in some cases, other hormone treatments. What you probably didn’t realise is that none of these methods is actually 100% reliable. In fact, condoms have a particularly high failure rate, at 18%[1]. The pill is an exceptionally popular choice. However, as a method of contraception it must be taken at the same time daily and it can easily be forgotten. In addition, when taken in conjunction with other medications, it can often prove ineffective.

A number of women still opt for hormones, including the pill, as their preferred method of contraception. However, there are a lot of facts that women still appear to be unclear on. For example, did you know that not only does it have the potential to affect fertility in the long run; taking the pill can actually increase your chances of falling victim to cervical or breast cancer in the future? Additionally, for every year it is taken, the cervix ages an additional year[2]. When you stop using hormone treatment, if your cycle returns to normal at all, it can take years before you are able to conceive.

The Lady-Comp is an effective, natural solution to your contraception concerns. By monitoring your basal body temperature, it provides simple data, indicating your most fertile days. This enables you to enjoy safe contraception without experiencing any of the adverse side effects. The Lady-Comp can also be used alongside other contraceptive methods that are not hormone based or invasive.

Please remember, although the Lady-Comp is an effective means of natural birth control, it does not protect you from sexually transmitted infections.

Stay protected!

Ovulation and family planning

Hoping to start a family? Well, for those that are trying, it can be an incredibly stressful time. You may find that your whole life becomes consumed by the desire for parenthood. All too often sex becomes a chore, rather than an intimate act of passion or love and, even for the most fertile amongst us, it can take up to three months to fall pregnant. However, that doesn’t make it any less worrying, or, indeed, put a stop to our impatience.


It’s true that when trying to conceive, many of us will try to predict when will be our most fertile day. However, this can prove wholly inaccurate because a vast number of us don’t actually conform to the typical 28 day cycle. The Lady-Comp eases this burden. The clever fertility computer uses stored information and your temperature readings to predict and indicate your most fertile days. A woman ovulates at the same time every month, within a 24 hour window. This egg can only be fertilised within a maximum of 18 hours. However, sperm can survive in a woman’s body for up to 5 days, meaning that it is possible to conceive by having sex up to 5 days before ovulation. With all of this in mind, the Lady-Comp will indicate on which days you are most likely to conceive.

Taking the stress out of trying for a baby, it provides a safe and natural alternative to costly and often harmful procedures such as hormone treatments, IVF, or artificial insemination, which may be the next consideration for many couples.

Get the family you’ve always planned for with Lady-Comp.

Daily obstacles

It’s true that the majority of us have hectic lifestyles. Living life in the fast lane means that even the simplest of tasks can become challenging. Indeed, most of us would forget our heads if they weren’t screwed on. But, luckily the Lady-Comp is cleverly designed to make life easy for us.

Many things could try to foil your attempt to track your cycle. What happens if you forget to charge the battery? Or your little ones get their hands on the device? Well, the Lady-Comp is clever and durable. Even if the battery dies, it will store all of your data, ready for when you turn it on again. In addition, it had been innovatively designed to ensure that stored data is intentionally difficult to delete. As such, it cannot be done by mistake, whether by yourself, or curious youngsters. Omitting the odd reading here and there won’t hinder its capability either. So, if you enjoyed a couple of glasses, or a bottle, of wine the night before, didn’t get much sleep, or you’re unwell, it is able to generate data itself over short periods. You can still use the Lady-Comp when you’re not feeling 100%, but it is recommended that you refrain from doing so until you’re fully better. This is because the fertility indicator could display when you’re temperature is higher than normal. We recommend that you still keep a regular diary of your readings where days are missed.

No obstacle is too big to overcome with Lady-Comp.

When do I use Lady-Comp?

LadycompIt’s recommended that we all try to keep a rough track of our cycle, as it enables us to watch out for abnormalities and gives an indication of unplanned pregnancy. From approximately age 19 we are able to do so.That’s because it is at this age our cycle typically becomes regular. As such, from then onwards, it is also possible to start using the Lady-Comp.

Have you just given birth to your little bundle of joy? Then you’ll probably be pleased to learn that it’s physiologically impossible to fall pregnant for approximately 6 weeks post partum. You should start using your Lady-Comp after this time. although it is unable to predict your first ovulation, it can confirm it. After which it will be able to predict fertility as normal.

Simply take your temperature with the oral thermometer as soon as you wake up and Lady-Comp will do the rest. Accurate to 1/100 degrees, it will determine fertility based on your basal body temperature. The innovative Chip III generation of Lady-Comp gives women a 6 hour window in which to take their temperature, as long as you have slept prior to doing so. This means it is still a viable option for those with erratic sleep patterns, due to shift work or caring for children etc. Essentially, it means that you could take your temperature at 7am on Monday, and at 2pm on Tuesday and Lady-Comp will still be able to formulate a reliable and customised reading.
