Am I ovulating? If so, how do I know exactly 'when' it happens?

Ovusense App Fertility App PCOS and conceiving
OvuSense can detect ovulation with 99% clinically proven accuracy, so you can take back control of your cycles.

According to clinical literature, only a small percentage of women ovulate bang on day 14 of their cycle, unlike we think. A clinical study by Wilcox et al. (2000) – study size 221, tells us that the 'fertile window' for women falls between cycle days 10 and 17 in only about 30% of women, which means that the majority of women are most fertile earlier in their cycle, and some much later.

You might be trying to conceive at completely the wrong time and not even realize it. The good news is, OvuSense can pinpoint your exact ovulation with 99% clinically proven accuracy. So, if you have been trying for six months or more, you can take back control and plan to conceive at exactly the right time in your cycle.

OvuSense is the only product on the market that measures your 'core body' temperature to accurately detect ovulation, unlike OPKs (ovulation predictor kits) which measure surges in LH (luteinizing hormone). Only OvuSense can confirm your ovulation with 99% clinically proven accuracy.

"We were scared that we weren't going to get pregnant naturally but OvuSense helped us get it right, and we didn't feel any pressure in our relationship. Three cycles with OvuSense and I was pregnant. It wouldn't have happened any other way as I was trying to conceive at completely the wrong time! Highly recommend OvuSense."

"I found out by using OvuSense that I have a 3 week Luteal Phase meaning we weren't having sex at the right time, second cycle on OvuSense and I'm pregnant. I would not have known otherwise; best money I have ever spent. Highly recommend buying OvuSense!"
Kirsty, 2015
"After 3yrs 4mths of TTC it's finally happened! If you need any proof that OvuSense works, I am officially pregnant! I’ve had my big, fat positive (BFP) this morning!"
Caroline, 2015
"I went for a check-up scan to make sure all was ok with my pregnancy. All is OK. My due date takes me back to conception on 4th April 2015, which is exactly what my OvuSense monitor told me. First cycle I used OvuSense and managed to get pregnant! Cannot recommend this machine enough."
Amy, 2015

How OvuSense works

OvuSense has two parts: medical-grade vaginal Sensor and App. OvuSense takes readings of your ‘core body’ temperature every five minutes, while you sleep, using a specially patented vaginal sensor. OvuSense avoids all external influences which can cause inaccurate readings in other temperature methods which use oral or skin sensors.

OvuSense can detect and calculate your ovulation with 99% accuracy

In just two weeks, OvuSense can tell you when you are going to ovulate this cycle and then confirm the date for you with 99% accuracy. OvuSense can then tell you your fertile window for the following cycle so each and every cycle, you know when you're going to ovulate.

OvuSense is accurate for every woman, even if you have extremely long cycles or suffer with ovulatory or hormonal conditions, such as PCOS

OvuSense works for everyone regardless of cycle length or absent periods and will detect and confirm your ovulation with 99% accuracy. In addition, OvuSense can also tell if you haven't ovulated each cycle, so that you can talk to your doctor and get help sooner.
