Struggling to conceive? The Lady-Comp Baby ensures stress free fertility awareness

Trying for a baby can be an extremely stressful time. Spending hours deciding on the optimum time to conceive, and planning everything right down to the last detail can be incredibly draining. And you probably didn’t bargain on it taking so long either. But even for the most fertile of couples, it can take up to three months to get pregnant. Indeed, many can become so obsessed with the notion of parenthood; it takes over their entire lives. All too often, sex becomes a chore rather than an act of passion or love. The Valley-Electronics Baby Comp takes all the stress out of trying for a baby. It is a highly reliable and effective fertility computer which makes a fantastic family planning aid, but also assists couples with reduced fertility challenges.

Stress less and put the fun into trying for a baby.

What is Lady-Comp Baby?

Want to know more? The Lady-Comp Baby is the very first fertility computer in the world that has been designed to help you conceive, as well as offer an effective method of contraception (through fertility awareness). It’s incredibly simple design features an easy to read LCD display and an oral thermometer, which neatly tucks away when not in use. With a database of more than 900,000 cycles stored within it, the Lady-Comp Baby is incredibly accurate and there’s no danger of suffering any adverse side effects. It simply takes your basal body temperature everyday and from this is able to accurately determine, analyse and display your individual fertility cycle.

Programmed using family planning research and boasting technologically advanced software, Lady-Comp Baby will register if you don’t ovulate or if you have a hormonal imbalance which could be responsible for early miscarriages. 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. Offering a safe and natural alternative to costly and often harmful procedures, such as hormone treatments, IVF, or artificial insemination, it is the perfect solution for those struggling to conceive. In a recent American study, 276 women who had experienced difficulties conceiving started using a fertility monitor. Half of these women conceived after one month of doing so. After just three cycles, 90% of the women had successfully conceived[1]. Clinical studies support the efficacy of the Lady-Comp Baby and have found it to be 99.3% accurate as an ovulation calculator. Please note: medications that affect your basal body temperature can reduce the accuracy of the readings.

What does Lady-Comp Baby provide for me?

Not only is the Lady-Comp Baby an accurate fertility calculator, it is also a pregnancy indicator and a natural form of contraception. The LCD display features the time, date, year, time zone and an alarm clock. All you need to do is map your cycle and Lady-Comp Baby will do the rest. It displays fertility, ovulation day, cycle day, 250 previous day readings and 6 days’ future predictions. In addition, it will show statistics for Body Mass Index, number of stored cycles, average cycle length, average temperature increase after ovulation and fluctuation on ovulation day.

As a pregnancy test, Lady-Comp Baby can predict probable pregnancy after 15 days (as soon as you have missed the first day of your period), and confirmed pregnancy after 18 days, with expected due date. There is also an option for gender prediction.

Three coloured lights represent fertility: red means fertile or ovulating (best time to conceive), amber means the Lady-Comp Baby is still learning your cycle or regular readings have been missed, and green means infertile (this can be used as a natural contraception method).

Ovulation and family planning

Ovulation & Family Planning

You’ve probably been planning the perfect little family in your head for years. Well, now the Lady-Comp Baby can help to get you there. Innovatively developed, it will predict and indicate your most fertile days, so that you’re more likely to be successful when trying for a baby. A woman will ovulate once a month and it is always at the same point in the cycle (within a 24 hour window). It 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’s possible to get pregnant by having sex up to 5 days before ovulation. There is even an increased chance of fertilisation the day before ovulation, rather than on the day itself.

Sex everyday is not the best way

Any excuse for a little bit of nookie! Well, it will certainly start out that way. However, once you go down the route of having sex as often as possible in order to conceive, it becomes less about enjoyment and more about requirement. Additionally, it may surprise you to learn that it could actually be counterproductive. Repeated ejaculations are thought to reduce a man’s sperm count and, as such, this could actually hinder your chances of becoming pregnant. Think counting 14 days into your cycle will be just as effective as using the Lady-Comp Baby? Wrong! Many women do not conform to the standard 28 day cycle, meaning that this method would prove entirely ineffective. On top of that, trying to track your cycle on your own can be emotionally and physically draining. Often it can cause stress and anxiety, which, in itself, is likely to reduce your chances of conceiving. Stress can also delay the release of an egg in women and reduce sperm count in men. With the support of the Lady-Comp Baby, you are completely aware of the days on which you are the most fertile. With this in mind, you will both be able to relax and enjoy trying for a baby. Trust us; sex everyday is not as good as it sounds!

Daily obstacles

Each day brings with it its very own challenges. Don’t let tracking your cycle be one of them!

When it comes to trying for a baby, the Lady-Comp Baby does all the hard work and leaves you to enjoy those intimate moments stress-free once again. Its clever design and advanced software means that nothing will get in its way and stop it from performing as it should. Even if you forget to give it a charge and it runs out of battery power, the internal clock keeps counting and your data will be perfectly stored for when it comes back to life. It has also been innovatively designed so that the data is intentionally difficult to delete. As such, it cannot be done by mistake, even if you have curious little ones that manage to get their hands on it.

although the Lady-Comp Baby will still work despite whether you enjoyed a couple (or a few) glasses of wine the night before, are ill, or didn’t sleep well, it is recommended that you don’t use it when you are not quite feeling 100%. This is because the fertility indicator may show when you have a high temperature. Omitting the odd reading won’t affect the reliability of the information, as the Lady-Comp Baby is able to generate missing data over short periods of time. However, it is best to keep a regular diary of your readings.

Each day needn’t be an obstacle course with the Lady-Comp Baby.

When do I use Lady-Comp Baby?

It’s always a good idea to track your cycle, whether trying for a baby or not. Tracking enables us to watch out for abnormalities that could be an indication of an unplanned pregnancy, or health concerns, including hormone/thyroid disorders, liver function problems, IBS and other conditions. It is recommended that we start this process from the age of 19, as this is the point at which a woman’s cycle typically becomes regular. As such, the Lady-Comp Baby can also be used from the age of 19 onwards. If you have just given birth to a little bundle of joy, you are physiologically infertile for approximately 6 weeks post-partum. The Lady-Comp Baby is unable to predict your first ovulation, but it can confirm it. After your first cycle it can start to indicate fertility as normal.

Accurate to 1/100 degrees, all it takes is the push of a single button for the oral thermometer to take your basal body temperature. It is important that you do this at the same time each and every day when you wake up. However, the innovative Chip III generation of Lady-Comp Baby gives you a 6 hour window in which to take your temperature, just as long as you have slept prior to doing so. This means it is still an effective tool for those that have an irregular sleeping pattern because they are caring for children, or that work shifts and sleep different hours during the week. Essentially, you could take your temperature at 7am on Monday, and 2pm on Tuesday and Lady-Comp Baby will still be able to formulate a reliable and customised reading.

Flexible and reliable; Lady-Comp Baby is ready when you are.
