Tracking your cycle in real time

Cycle 1

Start using OvuSense immediately by downloading data from your sensor each morning to the OvuSense App. Your temperature is tracked in real time.

After a few days, if you're using the OvuCore sensor, OvuSense can predict the onset of your ovulation without having to wait until the next cycle or rely on historic data.

Three days after you ovulate, OvuSense confirms the exact ovulation date. You can also continue monitoring your temperature to see what's happening with your progesterone levels during your luteal phase.

Cycle 2

Stop using the OvuCore Sensor during your period, recommencing use immediately after it ends. OvuSense will then predict the 8 days you are most likely to conceive in this cycle. If you're using the OvuFirst Sensor you can keep tracking throughout your period.

OvuSense updates the information it provides in real time during the cycle, replacing the 8 day 'long range' window with a 'short range' 4 day ovulation window.

Scroll on the OvuSense App to compare your ovulation dates and your cycle pattern. Real time data can be shared with your partner and/or doctor through the OvuSense Pro clinician portal.

Which fertility monitor is right for me?

Compare OvuSense with other methods for monitoring your ovulation and reproductive cycle.

As you consider which fertility monitor fits you best some typical things to consider are:

  1. How large a fertile window will it detect so you can maximize the time when you're trying to conceive
  2. How accurate is it at confirming ovulation - the less accurate the less chance of it helping you in your next cycle
  3. Can it predict ovulation using the current cycle data - something we like to call realtime prediction
  4. Does the system work for PCOS and irregular cycles
  5. Can it help your doctor screen for fertility issues
  6. Can it help you and your doctor monitor your medication or treatment

Each of the statistics quoted below are derived from clinical evidence available on fertility monitoring methods and products. Pro refers to the OvuSense Pro clinician portal. Click on the 'i' icon next to each method in the table, or directly on the method in the table on mobile devices to find out more about the clinical evidence.
