Sensiplan®

To measure basal body temperature, you will need an analog thermometer (i.e. glass with a liquid metal inside - preferably basal), or a calibrated digital basal thermometer (i.e. with two decimal places and a probe that can be inserted into an orifice - oral, vaginal or rectal routes are authorized).

The majority of hormonal contraceptives block the cycle by preventing ovulation. You will therefore unfortunately not be able to observe the cycle or practice the method as long as you are on hormonal contraception. You can do the first module then stop hormonal contraception to start Sensiplan® from the first natural cycle!

The copper IUD does not block ovulation, so it is possible to observe your cycle and ovulation with it! You can practice Sensiplan® with the copper IUD, and remove it when you feel ready.

It is possible to practice the method in these situations, but this will require more extensive and potentially longer follow-up (especially until the return of the fertility if you are breastfeeding).

I am also a certified instructor of the Billings Ovulation Method® which is an excellent method for these situations, and can use this knowledge to help you through these more challenging transitions.

The effectiveness of the Sensiplan® symptothermal method relies on abstinence from genital contact during the fertile period. Don't be afraid, with a little creativity, this is not synonymous with an absence of intimacy!
Some couples choose to use barrier methods such as condoms or ae diaphragm during the fertile window, in that case, it is the method chosen and its effectiveness that come into play. Keep in mind the use of barrier methods can disturb cervical mucus and make it less readable. Whatever your choice, I am here to support you and to inform you, but not to judge you.

Yes absolutely! It's the whole point of Fertility Awareness Based Methods when they are used for contraception!
The Sensiplan® symptothermal method makes it possible to know the infertile periods of the cycle with great precision, so you can enjoy sexuality with peace of mind.


When learning with an instructor, you can start having intercourse during the post-ovulatory infertile phase as early as the first cycle charting !

If you are self-teaching, please do not rely on fertility awareness for contraception until you are confident observing your signs, charting them, and applying the rules (at least 3-6 cycles). I offer stand-alone consultations if you want to go over your charts with me, I can check that you have understood the method correctly.
