A Fertility Tracker

Finding a good fertility tracker could be the step you need to take to boost your chances of pregnancy, and get pregnant when you want to. It’s difficult to pick the best one for you when you don’t know how they work and what they do. When you understand how different kinds of fertility trackers work, and how your body can help or hinder them, it makes it easier to find the right one for you. Fortunately, OvuSense is here to shed some light.

What Does Fertility Tracking Mean?

The sort of fertility tracking done by these devices could more truly be called ovulation tracking. They are not giving a measure of your fertility in absolute terms, but instead identifying the time in each menstrual cycle when you are fertile.

This time is known as your ‘fertile window’ and when it happens is defined by when you ovulate, how long an egg remains viable after ovulation and how long sperm can survive in your body after intercourse.

If you have unprotected sex at a time when sperm can survive long enough to reach the egg after it is ovulated, but before it stops being viable, then that egg could be fertilised, and you could get pregnant. As sperm survive around five days in a woman’s body and eggs are viable for no more than a day after ovulation, this gives you a fertile window of six days. Five days before ovulation, and one day after.

If you try hours or days outside this window then a slim possibility remains, borne by the chance that a small number of sperm may be especially long lived or fast moving or an egg that could endure just a few hours longer than usual. More than a day or so outside your fertile window, and there is simply no hope that fertile sperm and viable eggs could meet.

Tracking Ovulation

Fertility trackers work by determining when you will ovulate, and notifying you when you are in your fertile window.

OPKs and BBT tracking both work by identifying when you’re ovulating and applying that insight into your menstrual cycle to future months. This is acceptable if you have a regular cycle and if you get good answers about when you ovulate. If you have an irregular cycle or don’t get an accurate answer about when you ovulate, it’s harder to use these methods to predict when you will be fertile.

OvuSense gets you answers you can rely on. We track your core temperature with a specialised sensor, to get you accurate data. Our clinically tested algorithm turns this data about how your core temperature changes into information about your progesterone levels. This maps to how your body is preparing for ovulation. It cuts through the hormone confusion caused by PCOS, and gives predictions you can work with even when your cycles are irregular.
