Frequent questions from our clients

Are the fertility monitors reliable from the first day of use?

Yes! You can trust the comps with 99.3% reliability from day one. Expect to get more RED/YELLOW days in the first 3-6 months of use, however, as the comp is still “learning your cycle”. The number of GREEN days will increase with time and regular use of your comp.

Can you use the fertility comps if you have irregular cycles?

Yes. The comps are designed to handle cycles of varying lengths.

When, after stopping hormonal contraceptives, can I start using my Lady-Comp?

If you have stopped taking hormonal contraceptives, you may start using your comp as soon as you receive it or you may wait for your first natural bleed to return before commencing with your comp. The first bleed, after stopping an hormonal contraceptive, is a withdrawal bleed so some prefer to wait for this to pass. You can trust your Lady-Comp either way.


Can I accidently delete my temperature readings or will my data get lost if my comp loses power?

No. It is very difficult to “accidently” delete information off your Lady-Comp and the data will be saved in the event that the comp loses power.

Lack of sleep or high alcohol consumption can influence the temperature readings. Can I rely on the device anyway?

Yes. If your reading is influenced by a bad night or by drinking large amounts of alcohol it is recommended that you skip the temperature reading for that day. Omitting a reading once in a while isn’t a problem, the fertility indicator will remain reliable and Lady-Comp will react accordingly. Any “out of the norm”  temperature readings will, depending on the phase of your cycle, either be recognized and ignored as an exception or the device will show a yellow or red light to be on the safe side.

I have a baby, which means I have irregular sleep patterns and often have to get up during the night. Can I use ‘Lady-Comp’ anyway?

Yes. The general rule of thumb for NFP (natural family planning) using BBT (basal body temperature) is that an accurate measurement requires at least 5  hours of sleep. Temperature readings should be skipped if less than 5 hours of sleep have occurred, the night before. Lady-Comp is designed to still give reliable fertility indicators if temperature readings have been omitted, but only if omitting readings isn’t the rule.

What if a woman has had five hours of sleep, but they are not consecutive because she has woken to feed her baby, for example? The answer to this question is slightly more complicated and may depend and vary on the situation, for example:

  • If you wake up, before your normal waking time and within your 6 hour window period* simply take your temperature before getting up or active.
  • If your baby wakes for a feed before the measuring time and before your 6 hour window period*. You should be able to attend to the baby and then return to sleep and get enough sleep to wake at, your usual time, to take your temperature.
  • If you have had to wake numerous times throughout the night resulting in minimal sleep, it is recommended you skip the reading for that day. You can still rely on Lady-Comp’s daily fertility forecast . If you have a high number of “skipped” readings in a cycle the number of green days, for that cycle, will be decreased and replaced with yellow/red days.

Generally, users develop a good sense of when a readings can be omitted or not. We are always available to advise you further, should you need.

*6 hour window period : 3 hours before and 3 hours after the alarm time from previous day.

What will happen when I approach menopause?

Typically, when a woman approaches menopause, her cycles tend to become irregular due to delays in or failure of ovulation. Lady-Comp will pick up these irregularities and start to show more “yellow” days. You will be able to observe and learn how your cycle is changing during this stage of womanhood.

Sperm can remain alive and active within the female body for up to 6 days. Does the Lady-Comp take this into account when forecasting fertility?

Yes, Lady-Comp learns your individual fertility pattern and will forecast red/yellow days to cover your entire fertile period plus a couple of extra days to account for early or late ovulation.

How does the device handle time shifts when you are travelling?

Very well. You can simply reset the clock to the local time of your destination and continue to measure as usual. Lady-Comp is small and conveniently fits into you hand luggage to travel with.

How long does shipping take?

Delivery usually takes 1-3 working days, to arrive at your destination, from proof of payment. Deliveries to remote locations, on the outskirts of major cities, can take up to 7 working days.

I have just given birth to my baby and I'm still breast-feeding. When will it be wise to start using Lady-Comp?

Since the comps use ovulation and menstrual data to forecast fertility, it makes sense to start using the device once you are ovulating and your first new menstruation has returned.

Must I always let Lady-Comp wake me, or can I take my temperature even if no alarm has been set?

You only need to set your alarm for the first temperature reading (at the start of use) or if you have skipped more than 3 days of readings. Thereafter, you can turn your alarm off and wake naturally.

What is the Pearl Index?

The Pearl Index is the measurement of the level of reliability of a given method of contraception. e.g. If 100 women use contraception “X” for a period of one year and one of them gets pregnant despite correct application, contraception “X” has a Methodic Pearl Index of 1. It is important not to confuse the Methodic Pearl Index with the Application Pearl Index. The Methodic Pearl Index indicates how reliable a given method is if used correctly, while the Application Pearl Index also includes the number of undesired pregnancies due to disregarded rules of application.  This way there may be differing Pearl Index values for the same contraception method.  Lady-Comp has a Pearl Index of 0.7, if couples obey the daily forecasted fertility. This Pearl Index is comparable to other popular contraceptive methods.
