Effective ways to prevent pregnancy

1. How to prevent pregnancy naturally

Ejaculation outside the vagina

It is a method used by many men. Couples still have intercourse as usual, but when it comes to the climax, about to reach orgasm, the man needs to quickly withdraw the penis to ejaculate out, avoiding the semen falling into the woman's vagina. Ejaculation is also a way to have sex without getting pregnant.

This method of contraception can affect the pleasure of both men and women. In particular, it requires the man to have good control of excitement and determine the necessary time to withdraw the penis.

This natural birth control method is less effective at preventing pregnancy because even a small drop of semen can cause an unwanted pregnancy.

No vaginal intercourse

Two people just cuddling, caressing, giving each other sexual pleasure and of course not allowing the penis to enter the vagina. This is considered a natural method of contraception, completely harmless for both men and women. Anyone can use this measure to protect themselves and their partners.

However, when applying how couples should pay attention. If male pleasure leads to ejaculation, both partners need to let the semen out, not to stick in the vagina. If not, it is possible to conceive, especially in the days of ovulation.

This method requires both exercise of alertness and a high degree of restraint. You have to know how to control yourself, don't have sex too far or you will easily get pregnant.

Calculate ovulation to prevent pregnancy

This is one of the natural ways of birth control , based on the contraceptive mechanism of the menstrual cycle . This method of calculating safe sex days can be applied through the menstrual cycle. If you want to apply the method, you must track the last 8 menstrual periods to see if they are regular.

Depending on the body of each person as well as psychology, diet, and activities, the menstrual cycle of each person will be different. A normal woman's menstrual cycle lasts from 28 to 35 days.

How the menstrual cycle works:

  • Use for regular menstruation, 28-day cycle.
  • Each month, an egg is released on day 14 of the next menstrual cycle. They live in the fallopian tubes for 1 to 2 days, waiting for an opportunity to fertilize. Sperm can live for 5 days in the vaginal environment. Therefore, a few days before and after ovulation, the chances of conception will be very high.

Based on ovulation, it can be divided into 3 stages to calculate safe sex days as follows:

Stage 1: Relatively safe sex day

  • Count from the day you start your period to the 9th day . This is the time when eggs begin to gradually fall. If you have sex on these days, there is still a chance that the egg is still alive, if it meets the sperm, there is still a chance of fertilization.
  • Therefore, contraception at this time is only relative.

Stage 2: The most fertile period

  • You need to avoid sex on the days of ovulation in the middle of the cycle. The chance that the egg can meet the sperm at this time is over 90%. So if you have sex at this stage, it's best to use other methods of contraception.

Stage 3: Safe sex day

  • From the 20th day of one menstrual cycle to the first day of the next period is a wonderful time for couples. At this time, the egg is in the process of decomposition and preparing for a new cycle. In a nutshell, sex near the day of your period 8 days will be an absolutely safe day . Therefore, during intercourse, the sperm will not be able to meet the egg.
  • However, there are also cases of delayed ovulation because of health disturbances in a woman's menstrual cycle.

Note: For people with menstrual disorders , irregular menstruation, unstable psychology, this method should not be used. Because eggs can be released at any time.

Sex while breastfeeding

When you are breast-feeding exclusively and regularly for the first 6 months (do not give your baby anything to eat or drink), menstruation has not yet appeared, it is possible to have sex without getting pregnant. The reason is that breastfeeding increases prolactin levels in a woman's body, which helps prevent ovulation to prevent pregnancy.

However, not all nursing mothers apply this method successfully.

Sex during menopause

A woman's chances of getting pregnant wane over time. When a baby girl is born, she carries 1-2 million eggs with her. By adulthood, the number of eggs left is about 300,000. And only about 25,000 eggs remain in females after the age of 30.

As a woman turns 40, her chances of getting pregnant decrease. This doesn't mean that women over 40 can't get pregnant. When a woman goes through menopause, it means there are no eggs left in her body. Having sex at this time will absolutely not get pregnant.

The age when women will go through menopause occurs at 44 years of age onwards.

2. Using birth control pills

Daily birth control pills

Taking oral contraceptives daily is also one of the safe methods of contraception, which many women care about and use.

Vasectomy, sterilization

  • This method is very safe without affecting the health and pleasure of men during the couple's relationship.
