The Digital Basal Thermometer

If you’re trying to pin down the exact point each month when you ovulate, then one of the methods you can use is to measure your basal body temperature. This is the minimum temperature your body falls to in rest – a long night of rest, rather than simply sitting down for five minutes.

If you take this temperature daily, as soon as you wake up, you can use it to find out when you’re ovulating: it drops slightly the day before you ovulate, and then, when an egg is released it goes up by .2 degrees.


Getting an accurate reading can prove difficult however, as your basal temperature starts to rise as soon as you wake up and become active, and oral thermometers are limited in that they are only capable of giving a reading to the nearest tenth of a degree. This can miss subtle changes in temperature that may impact the overall accuracy of your prediction and result in you missing out on your best chance to conceive.

BBT monitoring also relies on using data from previous months to predict your current and future cycles. This can prove problematic for those with irregular cycles, or who are suffering from fertility issues such as PCOS (Polycistic Ovary Syndrome).

A Complete Solution

OvuSense offers a complete solution to these problems: a vaginal sensor that measures your temperature right through the night for the most accurate readings possible, and an algorithm-driven prediction that can alert you when you’re due to ovulate with 24 hours notice. The sensor measures the true fluctuations of progesterone throughout your cycle, which is then automatically entered into an app that uses this up-to-date information to predict the ovulation date of your current cycle, accounting for those with irregular cycles or fertility issues.

The result is an all-encompassing method that takes care of monitoring, tracking and prediction for you, and gives you the best possible chance of getting pregnant!
