Is femSense right for me?

While we would love for femSense to be suitable for everyone, it is important to note that this may not be the case. We encourage you to review the following information to determine if femSense is the right for you.

femSense may not be suitable for everyone due to several factors. If you have sensitive skin or allergies to medical-grade adhesives, the femSense sensor patch may not be suitable for you. However, you can still use the femSense app as a period and symptom tracker.

If you have irregular cycles or infrequent/absent menstruations, femSense relies on a regular cycle to accurately calculate the patch application day, so it may not be effective for you.

Weight conditions (underweight or overweight) can increase the risk of adhesion issues or skin irritations with the patch. If you have a BMI lower than 18.5 or higher than 30, femSense may not be right for you.

Keep in mind, excessive consumption of nicotine or alcohol can impact body temperature and potentially affect the accuracy of femSense in detecting ovulation.

femSense is not ready to support medical conditions such as PCOS. If you do not have a menstrual cycle between 21-35 days or take medications that affect body temperature, femSense may not be suitable for you.

If you are unsure whether femSense is suitable for you, please contact your doctor or get in touch with our technical support via e-mail to:
