I forgot when people started to promote "seven before and eight after" and "safe period contraception", but I can tell you clearly that there is still a great risk of pregnancy if you have unprotected sex during the so-called "safe period". This is not a joke.
"It's obviously in the safe period, how can I get pregnant? This is not scientific!" This is not unscientific, but you don't understand science.
"Safe period contraception" is a common name, which is similar to the professional medical terms "easy fertility period knowledge method" and "natural contraception method". Combine the length of the menstrual cycle and the physiological manifestations of the ovulation period (such as changes in cervical secretions and basal body temperature) to determine the easy fertility date in the menstrual cycle. The period outside the fertile period is what we understand as the relatively safe period.
Assuming that a menstrual cycle is 28 days, ovulation is around the 14th day. The 3 to 5 days before and after ovulation are the fertile period, which is the dangerous period for contraception. Days 1 to 7 and the last 4 to 5 days of the cycle are safe periods if ovulation has not occurred or the egg has died.
The answer is definitely no! The safe period does not mean absolute safety, but the chance of pregnancy is relatively low. First of all, experts point out that even if there is no ovulation, there is no rule that there is no condition for conception.
Secondly, the safe period is mostly used for women with very fixed menstrual cycles. The time of female ovulation determines the menstrual cycle. If the time of ovulation can be accurately calculated and the menstrual cycle is very stable, the chance of getting a contraceptive during this safe period is small.
But for women whose menstruation is not accurate, this safe period has no practical significance. Some people will have slight tingling or breast swelling and pulling during ovulation, but most of them have no obvious changes. It is difficult to grasp the timing without measuring basal body temperature.
However, if the ovulation date is not fixed, how can we determine when ovulation will occur? When is safe? It is only roughly estimated according to the so-called safe period algorithm, which is likely to cause errors in time. If you miscalculate the safe period, you may accidentally become a father! Therefore, if you don't want a child for the time being, just for the sake of a momentary pleasure, then you must take safety measures during the safe period.
1. Boys must have a "condom"
Don't blindly believe in safe period contraception. It will only increase the risk of accidental pregnancy. Nothing is absolutely safe. Only by taking good contraceptive measures can you have a greater chance of successful contraception. Men can wear condoms, which is a relatively effective contraceptive measure.
But here is the key point. Some people take emergency contraceptive pills for convenience, but according to surveys, only 80% of contraceptive pills can really prevent pregnancy. It can be seen that there is still a 20% chance of pregnancy, which is not very safe. Moreover, contraceptive pills contain hormones, which can easily cause irregular menstruation.
2. Contraception is not just for "contraception"
Secondly, contraception is not only to avoid the possibility of pregnancy, but also a way to prevent bacteria from entering the body. If bacteria and viruses breed in the tadpoles, they will directly invade the female body without the protection of condoms, which will cause unexpected damage to the body, cause inflammation, or get some infectious diseases, and even affect future pregnancy.
3. Be sure to confirm the "ovulation period"
If you insist on taking safe period contraception, you must confirm the ovulation period in advance. We might as well take the method of 3 before and 4 after menstruation, that is, three days before menstruation and 4 days after menstruation, which is safer.
Women will only ovulate once in each menstrual cycle, and the eggs will survive for 1 to 2 days after being discharged from the body. After 2 to 3 days of ovulation, the eggs will lose their ability to survive. It is very difficult to conceive at this time. If it is a woman whose menstrual cycle is not accurate, it is still recommended not to use safe period contraception methods as much as possible to avoid accidents.
In short, women do not have an absolute safe period. Women who do not want to get pregnant for the time being should not be lucky. Safe contraception is the key. For the sake of your own health, don't let your passion affect your physical health and future pregnancy.
