Ovulation and Temperature

When you’re trying to get pregnant, your temperature suddenly becomes very important. This is because, if you know what to look for, your temperature can reveal what’s going on inside your body, with processes that don’t show any obvious signs on the surface.

One of the processes that can affect your temperature is ovulation: if you can measure your temperature accurately over time, and know how it affects your average readings, you can identify and even predict when you ovulate, which can help you get pregnant!

Ovulation and Fertility

You can get pregnant in a relatively short period of time focussed on your ovulation date which is known as your ‘fertile window’. Sperm can survive for up to five days in a woman’s body after sex, while eggs are viable for a maximum of twenty-four hours after ovulation. This gives you a total fertile window of six days in which sex has the best chance of resulting in pregnancy.

Pro-actively identifying and predicting ovulation so you can be sure you are trying to conceive during your fertile window can boost your fertility and improve your chances of getting pregnant relative to someone who doesn’t know when they’re fertile, and one of the ways you can do this is by trackin your basal body temperature.

What is Your BBT?

Your Basal Body Temperature is the low, minimum level your body temperature falls to when your metabolism is at its minimum resting rate, for example, when you are asleep. If you take your temperature first thing in the morning, as soon as you wake up, before you even move from your bed, and track it over time, you’ll see how it changes. The pattern we’re looking for exists at the level of tenths of a degree, so you need a sensitive and accurate thermometer. Many women experience a drop in their BBT of a tenth of a degree across the three days before they ovulate, and everyone sees a rise of a tenth of a degree the day they ovulate.

Tracking Your BBT

It can be helpful to buy a fertility kit that takes on some of the burden of tracking your BBT and using it to predict when you will be fertile. These record your temperature themselves, and use the results to make predicts about your fertility.

OvuSense is different. Our specialised sensor tracks your core temperature to follow the rise and fall of your progesterone levels, which our algorithm can turn into an indication of when you will ovulate. Our app can start to provide you with predictions about when you will be fertile after only a few days of temperature readings, giving you more opportunities to get pregnant!
