TAKE BACK CONTROL OF YOUR FERTILITY: OvuSense™ is an extremely accurate cycle monitoring system, unlike any other fertility tracker on the market. OvuSense can predict ovulation up to a day in advance, in real time, and detects the exact date of ovulation with clinically proven 99% accuracy.
“I have been trying to conceive for five years. I signed up for the OvuSense App User Study when I saw they were looking for participants. Last month, I had my blood drawn to confirm ovulation, and the Doctor said I did not ovulate for the month of May. However, OvuSense said I did. My husband and I had sex all around the time OvuSense said I was in my ovulation window, and I woke up to...a positive pregnancy test. I’m so happy!” Courtney, 2016

“I want to express how horrible ovulation predictor kits are for women with PCOS. I never had a positive or even close to one in all the months I used them. OvuSense confirmed ovulation on Wednesday Feb. 24th 2016 and I’m now pregnant! This OvuSense machine is amazing!! If you are considering buying…do it. So worth the money.” Eden Nicole, 2016

“I am pregnant after using OvuSense for two months. We were trying for 8+ years before that.” Kirsty, 2015

“OvuSense confirmed my exact ovulation date. I was amazed how late it was in my cycle! I had no idea how late I ovulated and I would have never guessed on my own. I knew that I might not ovulate every month, but at least I knew that I had this month. I never would have of have known that, or ‘when’ it was, if I didn't have OvuSense!” Jenny, 2015

Worth every penny


Ovusense is worth the $35 a month for the subscription. I love this thing! I have PCOS so my cycles are super irregular, and I started taking my basal body temperatures the old fashioned way to track ovulation, but I was frustrated with how inaccurate my oral temp was day to day if I had a poor night sleep or woke up at a different time. Ovusense tracks your core body temp which makes it super accurate. You just put in the sensor overnight like a tampon (it's small and made of silicone so super comfortable) then take it out each morning and upload the data. I now know I'm ovulating and I had no idea! Ive now started to track my cervical mucus too. Try this thing out, it's sooo much easier and more accurate than taking your oral temp each morning.

Grateful for data and info


Thanks to OvuSense, my husband and I have put a mental re-start on the clock in terms of trying to conceive. Yes, the last year was hard with all of the negative tests, but in reality, our timing was always off because I didn't realize I was ovulating later in my cycle, so it's not surprising we didn't conceive—we weren't giving ourselves our best chance. Now we can move forward with the knowledge OvuSense provides. For the first time in a while, I feel much more optimistic. I am also grateful for the Facebook support group where I found a community of women who are so kind, empathetic, and generous with their advice.



Customer service is excellent.
The product I’m not so sure. I received my sensor and nfc in the mail and nfc would not let the sensor connect. I emailed support and they 2 day shipped a new nfc. Still won’t connect and I noticed on the sensor the silicone is sliced open. After sending in pics then are now replacing the sensor. I bought a year subscription . So I’m hoping the new equipment will work properly. Will update on product more after I get new.
