Learn to calculate your menstrual cycle

To calculate your menstrual cycle, is very simple ! All you have to do is write down the start of your period on a calendar for a few months to figure out how to count your cycle days and calculate the average length of your menstrual cycle.

First of all, ndo you ton first day of rrules on ton calendar it defines your first day of cycle. From this day forward, count each day until your next period. The day before your next period is the last day of your menstrual cycle., cThat's when you stop counting. This is how you find the number of days in your menstrual cycle for that month.

Next this method for a few months, you will be able to count the number of days in your cycle and you will be able to calculate the average length of your cycle. To do this, add the number of days in each cycle. Then divide that number by the number of cycles (i.e. the number of times you had your period) that you counted. This will give you the average number of days between each period or the average length of your cycle.

The ovulation calendar only gives probabilities. Fertile days are only approximate. The ovulation calendar is not suitable as a method of contraception.

The length of the female cycle can vary from 21 to 35 days. The fertile days are located more or less in the middle. The female cycle usually consists of four phases :

1st phase you cycle : the rules

The first day of menstruation always marks the beginning of a new cycle. Menstrual blood loss = chute estrogen and progesterone levels. The uterine lining is detached, because no fertilized egg has implanted there.

2nd phase you cycle : follicle maturation

Acalled « phase follicular ». Who is the maturation of around 40 to 100 follicles.

3rd phase you cycle : l’ovulation

These are the fertile days. During the ovulation phase, the unfertilized egg leaves the ovary and migrates into the fallopian tube. On its way to the fallopian tube, it can be impregnated. Each month, several eggs develop, but only one matures.

4e phase du cycle : the luteal phase

The egg now migrates through the fallopian tubes to reach the uterus. The residual corpus luteum begins to produce progesterone. This ensures optimal implantation conditions for the uterine mucosa. The body temperature then increases by about 0.25 to 0.5°C. If the temperature remains high for at least three days, you can be sure that ovulation has occurred. If the egg is not fertilized, the corpus luteum begins to break down and gradually stops producing progesterone (and estrogen). If a fertilized egg has successfully implanted, the corpus luteum is retained for about three months
