Luteal Cycle

When you’re trying to get pregnant, you’ll find yourself learning a lot. The more you can understand the processes that feed into your fertility, and the factors that can raise or lower your chances of getting pregnant, the better chance you have of conceiving when you want to, or at least knowing what you have to do to give yourself a better chance.

In this reading, the first half of your menstrual cycle is likely to get more attention. It’s in this follicular stage that your body matures and releases an egg, so it’s natural to think that understanding and optimising it is your key to conception. The second half of your cycle is just as important, however, and problems here can impact your chances of conceiving just as much as issues with ovulation.

After your ovaries release an egg, your body shifts its focus. The sac that the egg was maturing in grows into a form of biological transmitter, a temporary addition to your endocrine system called the Corpus Luteum. This creates the hormones that direct your uterus to create its lining. It’s this lining, known as the uterine lining or endometrial lining, that a fertilised egg will anchor into when it leaves the fallopian tubes and begins to develop into a foetus. If that lining is too thin, the egg won’t be able to anchor properly, and so you might not be able to get pregnant even if you’re ovulating to a regular schedule.

One of the main things you need to track is the length of your Luteal Phase. For most women it lasts between 12 and 14 days, allowing for a thick, healthy endometrial lining. If it lasts longer than ten days this could be a factor in difficulty getting pregnant, as it can’t anchor and sustain the egg as it grows.

You can time your Luteal Phase by keeping track of when you ovulate and when your period starts: your luteal phase is the time between these two events, with the start of your period signalling the beginning of your cycle.

The first day of your period is relatively easy to identify – it’s the first day of bleeding, rather than merely spotting. Ovulating can be harder to identify, and this is where OvuSense can help.

Using your Basal Body Temperature, or BBT, we can identify the day you ovulate, as well as providing predictions for future ovulation dates and fertile days. With these two events marked on your calendar, you can track the length of your Luteal Phase, and identify and address any Luteal Phase defects with a fertility professional.
