The principle of observing the cervix:

  • During the infertile time (after your period and after ovulation) the cervix is closed, hard and low (a bit like the cartilage in your nose).

  • During the fertile time (around ovulation), your cervix is soft (like a lip/earlobe) and more upright than in the infertile time.

To help you recognise the change, you should start examining the cervix immediately after your period. Be sure to always examine in the same position and with the same finger. For example, you can be standing up with one foot on the edge of the bathtub, or lying down or in a sitting position.

How to examine the cervix: 

  • after using the toilet, insert a clean finger into your vagina, move it up and toward the back, and feel your cervix with a circular motion.
  • Find the opening and assess the degree of opening (in women who have already had a natural childbirth, the cervix is never completely closed). Feel the rim around the opening: Is it soft or hard?

Please note: with the symptothermal method, in addition to the temperature, it is also necessary to observe the cervix or the cervical mucus. For the evaluation with trackle, however, you only need to enter the cervical mucus quality in the app, as this is easier for most users. The position of the cervix is not included in the evaluation. If you want, you can also observe it.
