Safe -popping, is it really safe?

Many female friends are very puzzled, and they obviously have the same room for the safety period, but they are still pregnant.Is the safe period contraception reliable?

In the final analysis, the effect of contraception is nothing more than successful, and it becomes a "person".

At present, there is no perfect and 100 % method of contraception. What we can do is to choose a more effective way and more suitable for ourselves.However, in actual life, many people are very superstitious about safety during the safe period. I feel that as long as they are clear, they do not spend money, do not take medicine, do not target the body and have no side effects.Happiness, how good!But there are quite a few accidental pregnancy.

Therefore, safety during safety is a very unreliable contraceptive method!IntersectionIntersectionIntersectionIntersection

First of all, let’s find out what is the safety period contraception!

Safe contraception, also known as natural contraception, is based on the time of women’s reproductive physiology to speculate on the date of ovulation, and to achieve the purpose of contraception during the judgment cycle.The failure rate of security contraceptives is very high, up to 14.4%to 47%.

Safety contraception includes calendar tables, basic body temperature methods, and cervical mucus observation methods.

Calendar table

Suitable for women with cyclical rules.Women’s menstrual cycle is different, and 21-35 days are within a normal physiological range.However, no matter how long the menstrual cycle, ovulation usually occurs around 14 days before the next menstruation.

A woman is excreted every monthly cycle of the menstrual cycle. After the ovaries are excreted ovarian, they can survive for 24 ~ 48 hours. The strongest essence is 24 hours after ovulation.The sperm can survive for 3 to 5 days in the female reproductive tract, so 4 to 5 days before and after ovulation is a susceptible period, and other times are the safe period.Even so, the endocrine conditions of women are easily disturbed by various factors, such as excessive fatigue, emotional fluctuations, drug interference, environmental changes, etc., ovulation time does not follow the conventional cards, and the possibility of recruitment is relatively high.

For women with irregular menstrual cycles, there is no basis and significance to estimate the menstrual cycle, and ovulation is even more elusive.

Basic body temperature method

Basic body temperature is what the human body wakes up after a long period of sleep, and has been measured before any activity.Women’s progesterone excitement is excited about the temperature regulating center of the mound brain, which can increase the basal body temperature by 0.3 ° C ~ 0.5 ° C after ovulation.Clinically, it can be used to determine one of the signs of the ovulation date.However, due to the influence of various external factors, the relationship between the curve of the basic body temperature and the ovulation time is not constant, and it is more troublesome to measure, and it is easy to interfere with the measurement results.

Cervical mucus observation method

The ovulation period is affected by estrogen, the amount of cervical mucus secretion increases, the mucus is thin and transparent, and the drawing degree can reach more than 10 cm.If the mucus is checked, the leaf -shaped leaf -shaped crystals can be seen after drying.After ovulation, the effect of progesterone has gradually decreased, the texture becomes sticky and turbid, and the brushes are poor, and it is easy to break.However, this observation requires training to master.

As the so -called "often walking by the river, how can there be no wet shoes?"

Because ovulation is easily affected by the outside world, environmental, climate, emotion, health and other factors may be delayed or advanced in advance, people are not as good as heaven!Therefore, no matter when XXOO, it is best to take safety measures.After all, the life is close to the sky, it is important, please choose the contraceptive measures that suits you!
