Auntie generally refers to menstruation, and how many days after menstruation is ovulation depends on the menstrual cycle and the length of the period. Since everyone’s menstrual cycle is different, the exact time of ovulation needs to be analyzed on a case-by-case basis. Usually, the day of ovulation is 14 days before the next menstrual period, and 5 days forward and 4 days backward are counted as ovulation, so if a woman has a 28-day menstrual cycle with a 3-day menstrual period, the day of ovulation is 11 days after the menstrual period is clean, and the period of ovulation is between 6 days and 15 days after the menstrual period is clean. However, if the patient’s menstrual cycle is delayed, the corresponding ovulation period will be different. Considering the individual differences, if you want to determine whether you are ovulating now, you can go to the hospital for ovulation monitoring through ultrasound.
