The ovulation period is the period with the highest success rate of conception. The possibility of having sex during this period is very high! So, many couples who are actively preparing for pregnancy will try their best to understand the ovulation day. So, how to calculate ovulation day? Today, the editor will introduce several methods for calculating ovulation days.
How to calculate ovulation period after menstruation?
Calculation method
Usually, women ovulate about 2 weeks (12-16 days) before their next menstrual period. Therefore, one can calculate based on their previous menstrual cycle patterns. However, due to the influence of environment, disease, mood, and medication, the ovulation period may also change, so calculating the ovulation date should be based on the actual situation.
Travel date calculation method
It is believed that each ovulation should occur about 14 days before menstruation, so the period from 5 days before ovulation to 5 days after ovulation is called the "ovulation day". However, this method is not very reliable because most women have irregular menstrual cycles. Compared to the first two methods, the first two are more reliable but somewhat cumbersome. Here we introduce a simple and reliable calculation method, hoping to be helpful to you. The calculation formula is:
The first day of ovulation is equal to the shortest menstrual cycle minus 18 days
Last day of ovulation=longest menstrual cycle days minus 11 days
Before using this formula for calculation, I am required to observe and record my menstrual cycle 8 times in a row to determine the longest and shortest days of my menstrual cycle. The numbers obtained by substituting the above formula represent the start and end times of the woman's ovulation period.
The calculation of menstrual cycle is from the first day of the next menstrual cycle to the first day of the next menstrual cycle. For example, the longest menstrual cycle of a woman of childbearing age in the first 8 months is 30 days, and the shortest is 28 days. Substituting it into the formula is:
Ovulation Day 1=28-18 days=10 days
Last day of ovulation=30 days -11 days=19 days
That is to say, this woman's ovulation period begins on the 10th day of her menstrual cycle and ends on the 19th day of her menstrual cycle.
If through observation, your menstrual cycle is very regular: once every 28 days, then you can set the longest and shortest days of your menstrual cycle to 28 days, and substitute them into the formula to calculate your "ovulation period" as: the 10th to 17th day of this menstrual cycle.
This calculation method is based on the first day of the current menstrual cycle and calculates the number of days backwards, rather than using the next menstrual cycle as the basis and calculating the number of days backwards, so it is not easy to make mistakes. After identifying the "ovulation period", if you want to get pregnant, you can start having sexual intercourse every other day from the first day of the "ovulation period" for several months, which is highly likely to lead to pregnancy. If you don't want to get pregnant, you have to miss the ovulation period and have sex.
Aquino Law
The Aquino method, also known as the mathematical formula method, refers to the ovulation day that starts 14 to 15 days before the last day of the menstrual cycle (i.e. the first day of the next menstrual cycle). If the day of the next menstrual cycle is on the Nth day, then this ovulation day is on the N-14th day.
Although the length of the menstrual cycle varies from person to person, and even for the same individual, the lifespan of the luteal phase is 14 days, which is constant. Changes in the menstrual cycle are caused by differences in the follicular phase. So we can use mathematical formulas to simply predict ovulation day.
Cervical mucus method
Cervical mucus appears throughout the menstrual cycle and has subtle periodic changes. We know that endometrial glandular cells in the cervix can secrete mucus, and the secretion amount and chemical and physical properties of mucus have significant periodic changes.
Just after menstruation, the secretion of mucus gradually increases and becomes thin and transparent, similar to egg white, reaching its peak before ovulation. It can also be said that the day with the highest mucus volume has the highest probability of ovulation.
At this point, by inserting your fingers deep into the vagina and dipping them in some mucus flowing out of the cervix, you can stretch the mucus into thin threads that can grow up to 10 centimeters in length. After ovulation, under the action of progesterone, the secretion of mucus is significantly reduced, thick and turbid, with poor extensibility, and easy to break when stretched. Understanding the changes in mucus patterns, if you observe and record the mucus state every night, you can easily find your ovulation day.
Middle pain method
Some people experience pain in their lower abdomen during the period between two menstrual periods, which happens to be the time before ovulation, known as middle pain or ovulation pain. Experts have investigated that 97% of intermediate pain is felt before ovulation, so if there is intermediate pain, it can be considered that ovulation will occur within 24 hours. For some people, this method may be the simplest and most feasible approach, but the disadvantage is that a small portion of them do not have intermediate pain and cannot use this method.
The above are the calculation methods for ovulation days recommended by the editor today. If you want to understand your ovulation period, you can come and take a look! I hope it can help me accurately understand my ovulation day at home.
