  • Can I continue using the coil?
    Better not. Copper and hormone coils distort your cycle (see LADYpedia).
  • Do LADY-COMP®/pearly® devices contain plasticisers?
    No. LADY-COMP® cycle computers have been certified as medical devices, are food-safe and bio-compatible, and thus plasticiser-free.
  • I am currently taking the pill. How can I change to LADY-COMP®/pearly® in this case?
    Before you start using a cycle computer, you have to discontinue the pill. For as long as you take the pill, you will not have a normal cycle since the pill is a drug that switches off your body’s hormone production. As soon as you have stopped taking the pill, you may start measuring your temperature with your cycle computer.
  • I have recently become a mother and am still breastfeeding. When will it be useful to go back to the LADY-COMP® device?
    As our method of cycle control is based on knowing the moment of ovulation, it is best to start when you begin to ovulate again, i.e. you should start your daily measurement from the first period after giving birth.
  • My sleep rhythm is irregular (I get up during the night, sleep in at weekends…). Can I still use a LADY-COMP®/pearly®?
    The LADY-COMP®/pearly® was designed for such life rhythms, among other things. For one thing, the 6-hour measurement tolerance also suits women with frequent interruptions of sleep. Before measurement, you should however have slept 4 to 5 hours in a row. Should you wish to sleep longer in the morning, you may freely choose and set the measurement time by adjusting the alarm.
  • What about missing measurements?
    The high prognostic accuracy offered by your LADY-COMP®/pearly® will not be diminished by the cancellation of measurements. Where measurements are suspended in case of an illness, our cycle computer will easily adapt to the original status. 1 or 2 missing measurements will be extrapolated based on data gathered about your cycle so far.
  • When can I get pregnant then?
    A woman can only get pregnant on the day she ovulates. A female ovum remains fertile for 6 to 18 hours. Given that sperms stay fertile for up to 5 days, LADY-COMP®/pearly® accounts for a time span of up to 5 days from the day of intercourse to the day of insemination.
  • Will illness or other health problems impair data quality?
    Persons with an illness associated with a higher body temperature should preferably suspend measurement for the time being. Once you recover, you may continue your measurements as before. LADY-COMP®/pearly® will cope with data gaps and analyse your fertility with great accuracy. In any case: you should consult your family practitioner for advice in case of health problems.
