Fertile period in women with regular menstrual cycles are at day 14 +/- 1 to day of next menstruation, meaning that occurred on day 13 or 15 before the date of the next menstruation (the first day of menstruation counted as day 1). Example: if the first day of your period to come is expected on October 31, the fertile period is October 16 to 18.

• For women with irregular menstrual cycles, the first count cycle length for 6 consecutive cycles to obtain the longest and shortest cycles. Longest cycle minus 11, while the shortest cycle minus 18 and we found the fertile period. Suppose the longest cycle 30 and the shortest cycle 26, the calculation is (30-11=21) and (26-18=8). The fertile period lasts from day 8 to day 21. Ovulation calendar system is less useful for women with irregular menstrual cycles.

• Changes in the cervical mucus.

A woman considered to have the most fertile period if cervical mucus is clean, smooth and elastic and can reach length or a long gap of 10 cm without interruption It is associated with increased levels of the hormone estrogen in the body during ovulation.
