If you are a Lady-Comp user, you are already familiar with its notation system. After you take your temperature each morning, the unit will flash a green light if you are infertile, and a red light if you are fertile. Yellow lights, which should always be treated as red, may be seen during transition days or if your temperature is fluctuating abnormally. Because every woman’s cycle may vary by a few days and ovulation may also vary, the typical user can expect 8 to 10 red light days over the course of her cycle. You will find these occur in the days leading up to ovulation and for 48 to 72 hours after ovulation has taken place.

If you have noticed an increase in red light days, it is because ovulation was not detected for you. There are four reasons why this might occur.

1) You missed a temperature reading. If you miss a daily temperature reading, especially close to your ovulation time, Lady-Comp will have difficulty confirming your fertile days. If you are unsure if you have taken your temperature daily, Lady-Comp has a feature which will allow you to check this.

2) You did not ovulate. As a healthy woman, you can experience the occasional month in which you do not ovulate. If Lady-Comp is unable to isolate your fertile days, it will issue you red and yellow lights as a precaution.

3) Your ovulation is delayed. Many factors, including stress, travel, or change in exercise routine, can cause a delay in ovulation. Lady-Comp will continue to give you red and/or yellow lights until ovulation has been confirmed.

You have atypical temperature patterns. Most women experience an increase in their basal body temperature when they are ovulating. However, not all do. If this is the case with you, be assured you can still use Lady-Comp effectively. You will just want to be sure that you secure your basal body temperature during the same hour each day, and do not miss any of your daily readings.
