Our menstrual cycle

Our menstrual cycle appears when our reproductive stage begins, in our adolescence, and accompanies us until adulthood, when we reach menopause. The menstrual cycle is part of us almost our entire life and that is why it is essential to know how it works, especially if you want to know how to calculate fertile days.

Going into the matter, the menstrual cycle begins with the first day of menstruation and lasts approximately 28 days, although there are women who have a longer cycle of 31 days or slightly shorter.

To know your fertile days this is a first piece of information that you should know about you and your cycle: the days of its duration from the first day of menstruation to the day before the new menstruation.

Now, our menstrual cycle is made up of two major phases: the follicular phase and the luteal phase. If we take as an example the average menstrual cycle of 28 days, then the first 14 days belong to the follicular phase and the other 14 days to the luteal phase. Something you should know about the luteal phase is that whether your cycle is longer or shorter at 28 days, the luteal phase will always be 14 days.

The follicular phase begins with our menstruation that lasts approximately 4 to 6 days. At this time we eliminate through our blood flow or the commonly called rule, the endometrium that our apparatus player had prepared to be procreated but it was not (because we are not pregnant and therefore we have the menstruation). When menstruation ends, pre-ovulation begins, which is also part of the follicular phase, is when the embryo produces the estrogens it needs to mature the new ovum.

Ovulation = fertile days

The luteal phase begins exactly 14 days before your period arrives and begins with ovulation, which is usually day 14 or 15 of your cycle; then it becomes pre-menstruation when the ovum has not been fertilized and begins to disintegrate, that is, when you have not become pregnant. When the last day of this phase arrives, the cycle begins again.

Precisely and as you may have already realized, ovulation is the moment of the menstrual cycle in which your ovum is ready to be fertilized, so ovulation days are what we call your fertile days and the key data to calculate your fertile days.

How to calculate the fertile days

How to calculate fertile days becomes a simpler task when you know your body and you know how your menstrual cycle regulates youl, taking greater control of it. Once you get down to work, in the following menstrual cycles it will be easier for you to calculate them.

1. Find the length of your cycle

If you are starting from scratch with controlling the patterns of your body and calculating the fertile days, the first thing you should do is know how long your menstrual cycle lasts. For it, mark on your calendar the day your period arrives and count the days that elapse until just the day before your next period arrives. The total of the elapsed days (approximately 28) are the length of your menstrual cycle.

2. Mark the following periods

With this information you can start marking on your calendar the date of your next periods, as they are dates we need to calculate fertile days. If we continue with the example of the 28-day menstrual cycles, then mark your next menstruation every 28 days on the calendar.

3. Calculate your ovulation day

Now, do you remember that we told you that ovulation happens within the luteal phase and that this phase lasts 14 days? Well, this is the key you need to calculate the fertile days. From the day you marked your next period on the calendar, count down 14 days and mark that day as your ovulation and your most fertile day of all.

4. Calculate fertile days

Something very important that you should keep in mind is that not only are you fertile this day, but the ovulation effect extends 4 days before and up to 4 days after ovulation, so to calculate the fertile days in their entirety, take the ovulation day and mark 4 days before and 3 after that day; every day between those two marks you just made are your fertile days.
