When Do You Ovulate?

When you’re trying to get pregnant, the most important thing you can do to boost your chances of success is learning when you ovulate. It can be difficult to know when this key event will happen: different people have different lengths of cycle, so there’s no single ‘correct’ answer. It’s also possible to have an irregular cycle, so its different from month to month.

Why is Ovulation Important?

Pregnancy is only possibly during a surprisingly short time in each menstrual cycle. Sperm need to meet the egg no more than 24 hours after it’s ovulated – after this point the egg is no longer viable and can’t be fertilised. Sperm can survive for around five days in a woman’s body after intercourse, so if you know when you’re going to ovulate, you can count back five days to identify the start of what’s known as your ‘fertile window’ – the time when you stand the best possible chance of getting pregnant.

Your fertile window lasts until the day after you ovulate, so it’s only six days in which you can, realistically, get pregnant. It’s anchored by when you ovulate: this is when the egg is released, so you need to know when you ovulate to find out when to try to conceive.

A Part of Your Cycle

Ovulation is part of your menstrual cycle – the central part. It takes place roughly half way into your cycle, with the preceding half focusing on your ovaries preparing a healthy, mature egg and the succeeding half the time during which your body creates a thick endometrial lining in which the egg can anchor. These parts of your cycle are known as the follicular and luteal phase, and they normally of approximately equal length.

This means if you know how long your cycle is – by tracking when your period is – and it’s regular (always the same length, rather than differing month to month) then you can guess approximately when you will ovulate by finding the halfway point of your cycle.

Pinning Down Ovulation

If you want to identify your fertile to maximise your chances of getting pregnant, then approximating when you’ll ovulate isn’t good enough. Unfortunately many of the commonly available tests for ovulation can only tell you when you are ovulating (or worse still, when you have ovulated) – which means you have at most 24 hours of your fertile window left!

OvuSense can provide you with a longer term prediction, by using variations in your core temperature to map your progesterone levels. This a direct indications of your body’s preparations for ovulation, which means OvuSense can tell you well in advance when you’re likely to ovulate and therefore when your fertile window will be, giving you access to all of your fertile days, and more chances to get pregnant!
