How is the menstrual cycle calculated?
When a woman reaches puberty, menstruation is an important milestone that indicates that a woman has begun to become fertile. During the first 2-3 years of puberty, the ovarian function has developed but has not really been completed, the menstrual cycle in women has not yet entered a regular cycle. After that, the ovaries gradually complete and menstruation will follow certain rules to form the menstrual cycle.
The menstrual cycle is counted from the first day of menstruation until the first day of the next menstrual period. Some women have cycles lasting only 20 days, others up to 40 days or more, when cycles that repeat at a relatively steady rate are considered normal.
To accurately determine their menstrual cycle, women should observe at least 3-4 months and record the number of days that the cycle returns. The number of days of a cycle should be close to each other or not too much, or your menstrual cycle calculation will not be really accurate.
How to calculate the day of ovulation according to the menstrual cycle
The menstrual cycle and the day of ovulation are closely related. To determine the exact day of ovulation, a woman’s menstrual cycle must be regular and stable. The easiest way to estimate ovulation is by counting backward. In theory, you first need to determine exactly when your next period should start, based on the number of days that the cycle has been tracked in the past.
After determining the date of your next period, you just need to count back 14 days, which is the day you will ovulate in this cycle. Understood as a simple rule, any woman, no matter how long the cycle lasts, 14 days after ovulation will begin her next menstrual period. From there, we apply the opposite calculation method.
For example, if you have a 28-day cycle, the day you ovulate is day 14 (28-14=14); If you have a cycle of 32 days, the day you ovulate is day 18 (32-14=18), if you have a cycle of 20 days, the day you ovulate is day 6 (20-14=6).
However, in practice, it is very difficult for women to accurately determine the date of their next period. In case women have irregular menstrual cycles, this method of calculating ovulation is completely ineffective.
Therefore, usually, you can only identify the period of high ovulation. This means that after determining the date of your next period, you count back 12 days and then count down another 4 days. At this point, you will determine the 5 days most likely to ovulate.
Ovulation signs
In case women have irregular menstrual cycles, you can rely on other signs of ovulation such as:
Increased body temperature
Use a thermometer to monitor your body temperature every morning before getting out of bed, you should measure it at a certain time and repeat and record it in a monitoring table. When a woman ovulates, her body temperature suddenly rises from 0.3 to 0.5 degrees Celsius.
Use ovulation test strips
The principle of operation of this test strip is based on the change in LH hormone levels during the menstrual cycle. When the amount of LH in a woman’s urine reaches the highest concentration, the egg will be released after 12-24 hours, so it should be tested about 2 days before the day of suspected ovulation.
Ovarian ultrasound
This is also one of the most accurate ways to identify ovulation. After 2-3 days of noticing that cervical fluid is wet on underwear, women can go for an egg ultrasound for 3 consecutive days of suspicion to determine the most accurate.
Final thought
The cervix appears an oily and clear fluid, women feel like being closer to their husbands than usual, the breasts are enlarged and there is a feeling of tightness. For most days of the month, a woman’s vagina is usually light or sometimes a little dry, but around the time of ovulation, there will be more mucus.
