Hello: The menstrual cycle is regular, each cycle is 28-30 days, ovulation is generally about 14 days before the next menstrual period, and the ovulation period is within 10 days between 5 days before and 4 days after ovulation, which is also the fertile period.
If the menstrual cycle is about 30 days, the menstrual period that comes on August 7 and ovulates around the 23rd, and the 10 days between the first 5 days and the last 4 days of August 23 is the ovulation period, which is also the fertile period. Other days are safe periods.
However, it should be noted that the menstrual cycle is regular, and ovulation can be performed every month, but the menstrual cycle is prone to fluctuations, and the time of ovulation has changed. If affected by changes in mood, health, diet and medication, and changes in the living environment, ovulation may be early or delayed, and the ovulation date may be difficult to grasp, which increases the possibility of pregnancy, so the safe period is not the most reliable method of contraception.
