In the menstrual cycle of every woman there are days when there is most likely to become pregnant, and the days when the possibility of conception is minimized. Of course, this method of calculating the safe and unsafe days in women fairly unreliable, if you take it as a basis. This natural method is more suitable for women who have regular menstrual cycles, do not use other contraceptives, sexually active, and they do not represent horror likelihood of pregnancy.
Days in a woman Safe calculated only when the menstrual cycle. Otherwise, the method very inefficient and has no meaning count safe days and dangerous woman can only be provided if it is recording cycle or graphics is basal temperature. In such a situation will be clearly visible to the variability of the cycle in certain periods of her life, even taking into account the time of year.
Calculation account strife: safety is a lottery
As a rule, the highest probability of getting pregnant is in the middle of the cycle - ovulation. But every woman ovulate very individual, so given the characteristics, the calculation is made with an offset in a few days. Thus obtained from 8 to 10 days. That is, when the menstrual cycle of 28 days, may be regarded as safe 1-9 days and 19-28 days. But since sperm can live in a woman's body up to 2-3 days, dangerous days is considered to be from 8 to 21 days.
Today, many experts argue that this natural method is very unreliable. Many women are not well oriented as last month specifically at them. After ovulation in women may be twice a month, and can shift suddenly and occur, for example, at 3-4 days of menstruation, for whatever reasons.
If you really set out to identify their safe and unsafe days natural method, then use the best measurement of basal body temperature. Thanks to this graph, you can determine the day of ovulation. Basal temperature is measured in the morning immediately after waking up, getting out of bed. After time you will learn your schedule. With regular cycle, ovulation day will be about the same. Then you can say that can be considered dangerous days before and 5 days after ovulation.
Again, rely on this method can not. Measurement of basal temperature is used frequently to determine the days of conception than the safe days. Therefore, if the pregnancy is really not desirable, it is better not to tempt fate, and resort to a reliable means of protection.
Also, do not forget about another important point - the "safe days in a woman" does not give guarantees not catch the infection and sexually transmitted diseases. These methods are the most unreasonable and unreliable. The best advice is to take advantage of new advances in modern medicine!
