The OvuSense 90 Day Money Back Guarantee
OvuSense Ovulation Promise

We never promise pregnancy - no one can do that. Instead, OvuSense provides you with extremely accurate information you can ‘do’ something about. It puts you back in control so you can change your fertility future.

We know the information OvuSense provides every cycle might not always be good news for you. OvuSense is the only product that will tell you if you have ovulated each cycle but also if you have not. If you aren’t ovulating you need to seek clinical advice, and we understand that can be expensive.

We are confident that OvuSense will confirm if you ARE ovulating, so if you use it for 90 days in a row and ovulation is not detected, we will offer you the option to switch to an alternate sensor, or a full refund to help you seek clinical advice and treatment if that's needed. This ovulation promise is subject to the following terms and conditions:


  • You need to have received no confirmation of ovulation from OvuSense in any of your cycles of use.
  • You need to have used OvuSense for 90 days, not missed an overnight recording except during menstruation or spotting, and not had any obvious temperature rise which would have resulted in a confirmed ovulation if 1-2 nights weren't missed due to spotting.
  • At the time of your claim you must be less than 42 years of age.
