A woman fertile period changes during her monthly cycle. The egg matures in approximately the middle of this cycle, about 14 days prior to the onset of menstruation. The fertility period is estimated roughly as 6 days. Calculation of this fertile period based on the cycle can be quite inaccurate, especially in the case of women with irregular cycles.
Fortunately, other change in the woman's organism can indicate fertile and infertile periods.
Often used is the curve of the basal body temperature: in the first half of the cycle, shortly after the beginning of the menstrual period, the temperature is low, after the egg is released, it rises.
It has been observed that, during fertile days, a sample of saliva resembles "ferns", while during all other days only shapeless, "dotted" structures can be seen. This fact has been known for many years only to researchers and medical specialist. Now the miniature microscope is on the international market, readily available. Any woman can check her fertility anytime and anywhere.
Saliva is the easiest accessible body fluid. There is no need for complicated blood or urine tests. "Fern" structure starts 3-4 days before ovulation and ceases 2-3 after ovulation. The fertility period lasts less then one week. If a woman does not want to conceive, she should, during this period, either abstain from intercourse or use some reliable method of contraception. On the other hand, the "dotted" structure of the saliva sample generally indicates a "safe" period.
