The safe period after ovulation is safer. Seven lies about female contraception are not to be believed.

The safe period after ovulation is safer than that before ovulation. This is because some women sometimes ovulate earlier due to environmental changes and mood swings, so that the pre-ovulation safety period will be shortened, but they do not know it, so the pre-ovulation safety period is not safe. The chance for the ovary to ovulate twice in a menstrual cycle is very rare, that is, the second ovulation generally does not occur during the period from ovulation to the next menstrual cycle, so the safe period after ovulation is safer.

Some women rely on safe-period contraception, but in fact, the failure rate is very high. Except that the ovulation period of a woman may change slightly from month to month. Another important reason is to ignore the problem that male sperm have a certain survival time after leaving the body.

We know that the survival time of eggs is generally 24 hours, that is, about 1 day. But sperm survive longer in women than eggs, usually up to 2-3 days, or even longer in some cases. Studies have shown that human sperm can only survive in a natural environment in vitro for a few minutes.

The sperm that directly enter the female body can still maintain exuberant vitality because of the relatively suitable environment, and its reproductive ability can not be ignored within 2 days. This is probably the result of natural selection and evolution, creating a time lag that increases the chances of sperm and egg meeting.

Therefore, if women really do not want to get pregnant, whether it is a safe period or not, they should do a good job of contraception. In addition, when calculating the safe period and the critical period, they should have a surplus of a few more days, and it is best to take precautions three days before the safe period. So it won't cause an accident. If you are planning to get pregnant, you can also act in advance to increase your chances.

Although it is called the safe period, it is not really safe. Choose contraception in the safe period, and you must have some knowledge about the safe period in order to avoid the occurrence of pregnancy outside.

Seven lies about female contraception can't be believed.

Lie one

You won't get pregnant during the safe period.

Many women with more accurate menstrual cycles can calculate their own safety period. Each menstrual cycle of women is divided into menstrual period, ovulation period and safe period. Generally speaking penispumpe , there is no egg exclusion during the safe period, so there is no need to worry about the problem of sperm entering the body to make the egg pregnant.

Take stock of commonly used contraceptive methods

But you may not know that sperm can fertilize an egg within three days after excretion nice ass , but there are also reports that sperm retain the ability to fertilize a week after sex. Although the ovulation period is in the middle of menstruation, it may advance or postpone ovulation due to the influence of external environment, temperature, mood, health status and other factors.

Therefore, the method of safe period contraception is not reliable at all. Generally speaking, the method of safe period contraception is only applicable to couples who have regular menstrual cycle best ass , long-term cohabitation, regular life, mutual cooperation and understanding.

Don't be afraid of the trouble to keep taking contraceptive.

What kind of contraception are you using? Contraceptive, which you must take before sex, does not guarantee the safety of "whim" sex. Are these short-term contraceptive measures boring you already?

In fact, in addition to external condoms, oral contraceptive, built-in contraceptive rings, there are many quite effective contraceptive methods you do not know. For example, an intrauterine device that must be surgically implanted into the womb. All it has to do is to prevent fertilized eggs from growing in the womb.

Generally speaking, as long as there is nothing unusual, it won't cause trouble for sex for a year or two. Intrauterine contraception does not guarantee you against sexually transmitted diseases, but it is one of the most effective methods of contraception. Once placed, you can forget about it, and there is only a 1% failure rate.

This long-term method of contraception is undoubtedly the most effective and convenient. But it is also not suitable for people, such as extreme retroflexion of uterus, endometritis, salpingitis, vaginitis, uterine fibroids and other gynecological diseases or excessive menstruation and secretions. If you are interested in intrauterine contraception, you might as well ask an experienced doctor in a regular hospital.

The contraceptive effect of contraceptive is the same for everyone

The packaging of contraceptive, which is sold on the market, shows only a few types that are not suitable for people. So is it suitable for people to take, the effect is the same?

In fact, overweight women have a faster metabolism and need more hormones to prevent pregnancy. When they are in contraception, they will be hindered by too much fat in the body, which will greatly reduce the effect of drugs, and it is difficult to get rid of the influence of weight when "creating a baby". Therefore, they should be cautious when choosing appropriate methods of contraception and "making a baby".

Moreover, a lot of contraceptive has the effect of dissolving fat and may be stuck in the place where fat accumulates in the body, so it can't really play a role in the blood where it should be.

I would like to remind you that if you weigh more than 58 kilograms, it is best to ask your doctor to recommend other more reliable methods, such as an intrauterine device, or a combination of contraceptive and condoms.

The effect of contraception is foolproof.

Do you think it is foolproof to use contraception? You must know that when the doctor tells you how effective contraceptives are, it is also based on the premise of proper use. Although contraceptive and condoms boast 99% and 97% efficiency. But in fact, in practical application, the real efficiency of the two is 94% and 86% respectively. That is to say, it does not have a 100% effective contraceptive effect at all.

To ensure that contraceptive is effective, you should take it at the same time every day. If you don't try to combine it with your daily life, it can help you remember the time better penis pumping , such as after brushing your teeth every morning.

In case you forget to take it, read the notes carefully and see what you can do to make up for it. If the women who choose condoms have less secretion, they can apply some lubricating ointment to fix it tightly to prevent it from slipping, and the effect is better.

Lie five

If the penis is not fully inserted, that is to say, the man ejaculates in the woman's vulva instead of in the vagina, the woman will not get pregnant, the fact is that the sperm may enter the vagina and continue to move toward the uterus.

Lie six

Lavage after intercourse, that is, washing the vagina with a liquid such as water, soap or warm cola, can wash away sperm and prevent pregnancy, but the fact is that lavage is not an effective contraceptive and can cause vaginal infection.

Lie Seven

After the other party ejaculates in her body, if the woman urinates immediately, she won't get pregnant. The truth is that it doesn't work. Urine is excreted from the urethra above the vagina, so it does not wash away sperm.
