How to calculate the safe period for women most accurately

If pregnant parents want to get pregnant safely and quickly, they must first understand the safe period for women. So what is the safe period? When is the safe period for women? How to calculate the safe period for women most accurately? The following editor will give you a detailed introduction.

What is the safe period

When it comes to the safe period, we must first understand the female menstrual cycle. From the first day of this menstruation to the first day of the next menstruation, this cycle is called a menstrual cycle. In a cycle, there are three periods: menstrual period, ovulation period and safe period. The ovulation period is the day when a woman lays an egg. Generally speaking, the egg can only survive in our body for 2-3 days. If you miss this period, it will be difficult to produce an egg, and the chance of pregnancy will become smaller, and you can enter the so-called "safe period". There is a saying in the folks that the safe period is "seven before and eight after", which means that the seven days before the menstruation comes to the eight days after the menstruation, which can be called the safe period. Of course, this is only relative to women with more regular menstruation, and each woman's menstrual cycle is different, so you can't blindly believe it.

When is the safe period for women?

Except for the menstrual period and ovulation period, the rest of the time is a safe period. Women's safety period is divided into the safe period before ovulation and the safe period after ovulation. The period from the last day of menstruation to the day before ovulation is the safe period before ovulation. From the first day after ovulation to the day before the next menstrual cramps is the safe period after ovulation.

The ovulation period of women is generally about 14 days before the next menstrual period. To be on the safe side, we call the ovulation period, which includes the 5 days before and 4 days after ovulation, and the 10 days including the ovulation day. Generally speaking, the ovaries of women of normal childbearing age only release one egg per month. The egg can survive for 1-2 days after release, and the sperm can survive for 2-3 days in the female reproductive tract. The fertilization ability is mostly within 24 hours after ovulation. If it exceeds 2-3 days, the sperm will lose the ability to combine with the egg. Therefore, if you have sexual intercourse 2-3 days before ovulation and 1-2 days after ovulation, you may get pregnant. This period is called the fertile period or dangerous period.

How to calculate the safe period for women

Temperature method

1. Overview

The body temperature method is the most accurate method among all the calculation methods. It is to calculate the day of ovulation by monitoring the basal body temperature of women every day. What is basal body temperature? It refers to the body temperature of humans after waking up in the morning. Since there is no activity, this body temperature value is also the lowest in the day. Studies have shown that when women ovulate, the secretion of progesterone stimulates the hypothalamus, causing the body temperature to continue to rise, and it will not be relieved until the menstruation comes. Therefore, as long as you strictly follow this method for sexual intercourse, you can effectively prevent pregnancy and conceive.

2. Methods

First, in order to measure body temperature, you need to go to the pharmacy and buy a special basal thermometer. Next, starting from the first day of menstruation, measure your basal body temperature once every morning before getting out of bed, record it, and keep doing so for 10 days. Then, organize the data and draw a table. Here, we need to remind you that you must measure at regular times and locations, and make sure you sleep for more than 8 hours.

Then, check your highest temperature in the past 10 days. Add 0.15 degrees to this highest temperature, and this is the value you need to compare. Of course, if you have a fever during these 10 days, this data will be inaccurate and will have to be discarded.

Finally, you need to continue to monitor your body temperature every morning. When you find that it is higher than this value for three consecutive days, congratulations, your safe period has arrived. From the fourth day until the next menstrual period, you can safely arrange a relaxed sex life.

3. Notes

Although the temperature method is more accurate, it is not ideal because various physical reasons may cause the body temperature to rise during the measurement process, and it is impossible to accurately determine the ovulation day. The temperature method is more effective in calculating the safe period after ovulation, but it cannot predict the day of ovulation, so this problem still needs to be paid attention to.

Uterine mucus method

1. Overview

As the name suggests, this method is to determine the safe period by checking the uterine mucus. This method allows you to find the dangerous period, so as to avoid intimacy during the dangerous period, thus achieving effective contraception.

2. Methods

As women's ovulation period arrives, hormones in the body continue to rise, and a kind of mucus is produced in the vagina. You can use clean fingers or toilet paper to observe the mucus. If you find that the mucus gradually increases, becomes very sticky and slippery, and has a bright color, similar to the egg white we usually see, it means that the day of ovulation is coming. If you find that the mucus begins to become very thick and even cannot be found, it means that the day of ovulation is over. Of course, this method requires you to observe carefully and make some records when necessary to accurately determine the ovulation period.

3. Notes

It is safer to have sex 3 days after the uterine mucus disappears. In addition, you cannot have sex during menstruation, otherwise it will affect the accuracy. You can have sex during the safe period, but try to choose daytime when checking uterine mucus, because sperm remaining in the vagina at night will affect the secretion of mucus. This method is more complicated and should not be blindly believed. Contraceptives still need to take safety measures as much as possible. Friends who want to have a baby can use this method to find out the fertile period, which will help them get pregnant.

Calendar Method

1. Overview

This method is based on the menstrual cycle, so the first thing you need to figure out is what your menstrual cycle is.

2. Methods

First, you need to find a calendar and record in detail when your menstruation starts and ends each month. This record should be kept for at least half a year. The first day of your menstrual period to the first day of your menstrual period in the next month is a cycle. Next, pick the shortest and longest cycle among these cycles.

The first day of the safe period is the longest cycle minus 11, and the first day of the fertile period is the shortest cycle minus 18.

Finally, let me give you an example. For example, the shortest menstrual cycle is 28 days and the longest is 31 days. Then the safe period starts from the 20th day after the menstruation this month (31-11=20 days), and the fertile period starts from the 10th day after the menstruation this month (28-18=10 days).

3. Notes

This method has the lowest accuracy rate among the three methods, so you still need to maintain an objective attitude. In addition, this method is suitable for women with regular menstrual cycles, but not for mothers who have not fully recovered after giving birth or women who have entered menopause.
