Great number of women try to avoid using of chemical or hormonal contraceptives. There are a lot of reasons for this: side effects of such contraceptives, possible negative influence on health now or in future, individual reaction of organism and many others. For some people their religious convictions don't allow to use the contraceptives. The natural method of contraception is the safest method for health, suitable for almost all women. It has high effectiveness level (up to 95%). This method allows to have free sexual life during 18-20 days of cycle (for 28 days cycle). The natural method of contraception is based on the determining the date of ovulation and calculating the "unsafe" and "safe" periods. The "unsafe" period is the days before and following the ovulation, when an egg is released from an ovary and travels along a fallopian tube to the uterus. The conception is possible only for these days. This period can be calculated using the date of ovulation and the knowledge that the egg survives for 24-48 hours, and the sperm for a maximum of 72 hours. Ovulation occurs approximately 14 days before the next menstruation. During the "unsafe" period you must avoid the sexual intercourse or use other method of contraception: condoms or coitus interruptus. Using the information about your past menstrual cycles is possible to calculate the "unsafe" and "safe" periods. Femta performs much more complex calculations for you and displays not the simple "safe" days, but the probabilities to become pregnant for each day in the past and several months ahead. You can determine possible chances to become pregnant for every day and plan your sexual life. For women with regular menstrual cycles this method is reliable, but for women with variable in length cycles (which vary in length more than 2 days from month to month) it is necessary to use additional methods to determine the date of ovulation more exactly. There is the temperature(sympto-termal) method of determining the date of ovulation. (this method will be implemented in one of the next versions of Femta). Read the Ovulation topic for more details.

Note:This method is not suitable for a woman, if :
· Menstrual cycles are very irregular
· Cycles are shorter than 25 or longer than 35 days
· Working in the different time(day / night) or with the shift in time (stewardess, for example)

Note: Please consult with your doctor about contraception.

There is a complex method of artificial fertilization including the special processing of sperm. Also there are alternative methods based on a special diet or using age of parents and the date of conception. Femta allows you to try the method, based on the scientific biological information. Its main principle is using different activity and duration of life of the spermatozoon with Y-chromosome (which enables the conception of boy) and spermatozoon without this chromosome (which enables the conception of girl). · The closer the sexual intercourse to the ovulation day, the greater probability to conceive a boy. · Probability to conceive a girl is more if the intercourse occurs 2-3 days before the ovulation.
