Who can use femSense?
femSense is suitable for fertile women who bleed and ovulate. If your cycle is between 21 and 35 days and the cycles do not differ more than +/- 3 days: femSense is for you!
If your menstrual cycle is irregular, then femSense cannot reliably predict your fertile window. In this case we recommend that you consult a doctor before choosing femSense.
How many patches do I use per cycle?
You can use one patch per cycle. After applying and activating a patch according to the in-app instructions, the patch is associated with your current cycle.
How many patches will I need?
You will need one patch per cycle that you plan to use femSense. If your goal is to get pregnant, data from a recent study on women using natural family planning like femSense can help you determine how many you might require:
- 42% conceived in their first month of trying
- 75% conceived by their third month
- 88% conceived by six months
- 98% conceived by 12 months
How does the femSense patch work?
The femSense System consists of a very precise temperature sensor embedded in an adhesive patch and the supporting app.
Th femSense app prompts you to apply the patch when it estimates your fertile window. The sensor patch is worn underneath your arm. Once activated, the patch measures the body temperature continuously, 24/7, for up to 7 days. To work correctly the patch should be read by your NFC capable smart device at least once (1) a day. The app will ask you to read the patch twice (2) a day for optimal evaluation. femSense tells you when you are fertile and, based on the recorded temperature data, femSense can detect and confirm ovulation. Every month the app reminds you when to apply the patch, when to read the patch, and when you are fertile.
How accurate is femSense?
The temperature sensor used in the femSense patches detects temperature differences smaller than 0.1°C and was especially designed to detect the postovulatory temperature rise, which is typically between 0.2°C-0.5°C.
In contrast to the basic basal temperature measurement method the patch records a temperature value several times per hour. As the patch is always in the same position, measurement artifacts can be minimized. A clinical study with the medical university in Graz proved the accuracy of the sensor patch and now an independent Swiss statistics institute has confirmed that femSense is 99.73% accurate when predicting ovulation.
How does femSense know when I am fertile?
femSense reliably detects your ovulation and most fertile days using continuous temperature measurement and the well-known temperature method.
The femSense app predicts your fertile window, the days you will most likely get pregnant. The prediction is based on your previous periods. The femSense sensor patch measures your body temperature continuously, 24/7 during your fertile window to measure and confirm your ovulation. You are fertile in the days shortly before and immediately after ovulation.
Verified Success Stories
Thanks to femSense, I got pregnant in the 4th cycle. Using femSense showed me that my ovulation happens earlier than I had always assumed.
After several cycles trying to get pregnant, I started looking for a reliable cycle tracker. femSense seemed easy to use and I got pregnant the first time. I was sure I knew my cycle well before using it. However, the patch showed my ovulation two days earlier than predicted in the cycle apps. That seems to have been spot on. Without femSense, I would have missed my ovulation.
femSense takes away all the hard work and lets you enjoy the fun stuff. I found it easier than measuring with a basal thermometer every day, or doing ovulation tests every morning.
I used femSense for 7 months and it was totally easy to use. I couldn’t believe my luck. One day after my birthday I found out that we were pregnant. It was a wonderful and indescribable feeling.
Unfortunately, my cycle was quite irregular. I used the patches in combination with ovulation prediction strips and they both measured my ovulation. I had used just ovulation test strips previously. I needed the patch for 2 cycles. It was important to me that I could rely on the patch and to see everything in the calendar. Every couple shoud try the patches.
I had been trying for 8 months. My cycle was irregular and we had been through several examinations by doctors without finding anything. I couldn’t cope with taking my temperature and checking my cervical mucus every day! I only used one patch (I still can’t believe it
We had tried for 1.5 years to get pregnant, and finally it happened. Sadly, that baby didn’t want to stay with us, and I didn’t have the patience to wait any longer. After just one patch, it worked. I recommend femSense to all my girlfriends
I was pregnant after 3 months, using femSense was really simple and straightforward. It was important to me to get the timing right because we didn’t have many opportunities to try. I couldn’t believe it at first, now I am just grateful and happy, and I hope that everything will go well one last time and our family will then be complete. I would recommend femSense without hesitation - it gave me a safe and secure feeling that I was not missing the right time.
For the first two “practice cycles“ we used a urine ovulation test, but since I work shifts, it was difficult for me to stick to the schedule. I looked for alternatives, and femSense was the most suitable solution for us. The application is really very easy. My husband came home and the first thing he did was read my patch.
I got pregnant straight away, in the first cycle with femSense :) I thought it would take up to a year to get my hormones back on track because I had been taking the pill for so many years.
I used ovulation prediction tests for one cycle, I found them exhausting. The patch seemed like a great alternative. The application is really easy. I was skeptical at first about whether the patch would hold up in the shower etc., but it always stuck on really securely! You don’t even notice it. Don’t drive yourself crazy. If you are looking for a simple method that is effective and reliable, femSense is the right choice.
We had tried IVF for one year, but I had had enough so we needed to find an alternative. Because of the hormone treatment, my ovulation and menstrual cycle were all mixed up. femSense made it so easy for me. It was easy to understand and unlike other methods didn’t involve taking and charting my temperature myself. It was simple – stick on a patch, hold your mobile phone up to it in the morning, and that’s it!
I only used 2 patches before getting pregnant! Never stop hoping, one day you too will hold your happiness in your arms.
