How To Calculate Your Menstrual Cycle

Menstruation is one of the developmental changes that girls go through when they reach puberty. This only means that they are already mature enough to carry and bear a child. The menstrual cycle is actually divided into three phases namely the follicular phase as the first, the ovulation phase as follows, and the next one is the luteal phase, which after then goes back to the first cycle. The moment the woman’s body increase the hormone called estrogen, the body signals the walls of the uterus to slough off if no implantation happens.

It is important for one to calculate one’s menstrual cycle especially when you are planning on using the calendar method as a way of contraception or when you are trying to calculate when you will be due when you are pregnant. This is also a way of telling whether your menstruation is regular or not. If there happens to be changes on the cycle, this could mean that there could be underlying conditions in your body that you do not know of. So here are steps that would teach you how to easily calculate your menstrual cycle:
  1. So first thing’s first, you would have to take note which date you first had your menstruation and half that as Day 1 of your menstrual cycle. Most of the time the regular days of period would be 3 – 5 days, but others vary according to what is regular for them. Others may menstruate for a period of 1 week but they experience it on a monthly basis, so that is still considered as regular.

  2. If you want to know when your ovulation would be, you should have to count up to the 14th day from the 1st day of your menstrual cycle to get to the point when you are ovulating, this means that you are fertile and that any implantation of sperm on your ovaries would entail impregnation. The eggs of the females only last 1 – 2 days before it dies, so any union of sperm before that will not be mature to an embryo. If within this 1 – 2 days a sperm comes, the egg would travel down to the fallopian tube to imbed itself on the uterus’ walls, ready for pregnancy.

  3. Usually the menstrual cycle lasts only for 28 days, so you should expect your next period to come on the 28th day and that would already be considered as another start of your menstrual cycle. The period comes when no implantation of egg happens on the walls of the uterus.
Calculating your menstruation cycle is really important in order for you to find out when to expect, when is the best time to conceive if you are planning on getting pregnant, and when’s the best time to avoid coitus when you don’t plan on getting pregnant. You must also remember that not all women have the same menstrual cycles so you should not compare yours with them. Women’s periods vary so you must do your own calculations as well.

  1. The way you explain is really awesome. I used to have the worst PMS symptoms – mood swings for sure. But out of control sugar and fat cravings. Surprisingly, the more fat I ate, the less sugar I craved during my PMS.
    Next, I started a low(er) carbohydrate diet, keeping my daily carbs between 50-70 grams, pretty much every day. It’s been two months since I’ve been following this low carb and high fat (40% of calories to even 60% of calories) eating style, and also supplementing with fish oil and cod liver oil. These two months….NO PMS. For the first time in my 27 year old life. And I’m not on birth control since 8 months….everything’s steady, normal….
    A high fat (nuts, olive oil, eggs, meats) diet and a bunch of red meat has kept my PMS off…so no more falling off the eating/training cycle for 1 week ever 4 weeks.

  2. Menstrual Cycle refers to the time that starts from Day 1 of the first period and ends with Day 1 of the next period. Most menstrual cycles are between 25 and 36 days.
