Is femSense right for me?
We absolutely want femSense to work for everyone, but it's important to understand that it might not be the perfect fit for everyone. Don't worry, though! Just review the following information to determine if femSense is the right option for you.FeaturedWhat ingredients are used in the patch?
The adhesives of the materials used in the patch are acrylate-based. The adhesives of the materials that come into contact with your skin are latex-free and tested for biocompatibility. The materials on which the adhesives are applied are polyethylene (PE) films or foams and a non-woven fabric. Despite the greatest care in the choice of materials, local skin irritation may occur in isolated cases. This tends to affect people who are generally more sensitive to plasters.Few readersWhat is the luteal phase?
Your cycle consists of two phases: the follicular phase and the luteal phase. The luteal phase refers to the time after ovulation and before your next period and usually lasts about 12-14 days. During this phase, the corpus luteum is formed from the matured egg. This corpus luteum dissolves if no egg is fertilized. If it is fertilized, the hormones released by the corpus luteum provide the basis for a pregnancy. femSense determines the patch application day based on your period (= the end ofFew readersWhen can femSense not be used?
Certain medical conditions prevent femSense from reliably measuring ovulation. These include: Serious, acute, or chronic diseases Nicotine, alcohol, or drug abuse Oligomenorrhea (irregular menstrual bleeding) Polycystic Ovary Syndrome (PCOS) Being very over or underweight Hirsutism Hormone therapy Allergy to plaster componentsFew readersWhat is an anovulatory cycle?
Anovulatory cycles are completely natural and nothing to worry about. An anovulatory cycle is a cycle in which you do not ovulate. Such a cycle can be caused by lifestyle factors (jet lag, stress, exercise, weight problems) or due to medical circumstances (e.g. PCOS). Studies show that most women have one to two anovulatory cycles per year, for example in the course of an illness or due to stress.Few readersHow does femSense measure ovulation?
femSense uses the well-known temperature method to detect ovulation and takes it to the 21st century. Immediately after ovulation, the body temperature rises by a tiny amount. While this minuscule rise is difficult to determine using conventional thermometers and usually takes several days to get a result, femSense is capable of detecting this temperature rise while it's happening due to the continuous measurFew readersPatch markings on my skin - is that normal?
Depending on your skin type and your personal sensitivity, you could see markings on your skin where the patch was applied. As with any other adhesive or band-aid that is worn for several days, the femSense patch might leave a mark when it is removed. Another contributor to markings would be friction. femSense recommends putting the patch on your less dominant side (i.e. if you are right-handed, apply the patch on your left side). Always make sure the spot you chose is clean and void of any creFew readersWhy did femSense show a different ovulation date to my OPK?
Ovulation tests are used to determine when you ovulate and are most likely to get pregnant. Since the different methods of ovulation detection measure different bodily signals, they usually are “positive” on different days. While ovulation test strips measure the hormone that shows that the body is most likely preparing to ovulate, femSense measures your body temperatFew readersCan a Covid vaccination cause a skin reaction?
Vaccinations can trigger immune system reactions. If you are wearing a femSense patch when you get a vaccination, please watch out for skin reactions. If you experience skin irritation, please remove the patch and apply a soothing ointment to the area.Few readersCan I wear the patch during a Covid-19 vaccination?
After a Covid 19 vaccination, general reactions such as temperature increase and fever are known in addition to local reactions. They show that the human immune system reacts to the vaccine. If the patch sticking period overlaps with the vaccination, we recommend that you suspend this cycle as the vaccination may affect your body temperature and therefore the reliability of femSense may be affected.Few readersCan I use femSense, if I have PCOS?
femSense has not been tested for women with PCOS. femSense is most reliable with regular cycles between 25 and 34 days with a maximum deviation of +/- 3 days. The algorithm bases its prediction of your fertile window on previous cycles and the patch is only worn for a maximum of 7 days during this time. If the patch has not measured ovulation in this time the app will notify you and ask you to remove the patch. This means if you have a very long cycle after a few shorter cycles the app could prFew readersCan I use femSense if my cycle is irregular?
femSense is most reliable with cycles of regular length between 25 and 34 days. Shorter or longer cycles decrease the reliability of femSense. If you have very irregular cycles (a regular deviation of more than +/- 3 days), we recommend that you consult your doctor before using femSense. For information regarding femSense and PCO/PCOS, please see: Can I use femSense, if I have PCOS?Few readersMy skin reacts allergically to band-aids, can I use the femSense patch?
The femSense Patch is made of hypoallergenic materials used in medical wound care. However, some people with very sensitive skin may still react to the patch or the medical-grade adhesive.

If you are unsure whether femSense is suitable for you, please contact your doctor or get in touchSome readersCan I use femSense if I am sick?
That depends on the illness. If you are already wearing the patch when you get sick then continue reading the patch as normal, however, if you develop a fever you should remove the patch. If you have a fever before you apply the patch, or if your temperature is slightly elevated, we recommend, that you skip this cycle. If you are not sure, please ask your doctor. Certain medications can influence your body temperature and therefore femSense’s reliability. This will usually be mentioned in the mFew readersThat depends on the illness.
