How to calculate the ovulation period: Ovulation usually occurs about 12 to 16 days before the next menstrual period. The safe period is divided into the safe period before ovulation and the safe period after ovulation. The ovulation period calculator can accurately calculate the specific time of ovulation, safe period and menstrual period, but the premise is that the person's menstrual cycle is normal. If the menstrual cycle is abnormal or the number of days is inaccurate, the result will be inaccurate. Remember! Safe period: The probability of pregnancy is small, and there is no need to use contraceptive drugs and contraceptive tools. Ovulation period: The ovulation day and the 5 days before and 4 days after are the ovulation period. The possibility of pregnancy is greater during this period. Menstrual period: Please pay attention to menstrual hygiene
