Patient's question:
Hello, is it necessary to treat if your menstrual period is always delayed by eight or nine days? If you calculate the ovulation period based on the date, how should you calculate it? What is the highest pregnancy rate when having sex every few days during the fertile period? Thank you!Doctor's answer:
Hello, the method of calculating the date of ovulation. That is: it is believed that each ovulation should occur around 14 days before menstruation, so the 5 days before ovulation to the 5 days after ovulation are called the "ovulation period." However, this method is not very reliable because most women do not have such regular periods. Compared to the first two methods, the latter two are more reliable but can be a bit troublesome. Here, we introduce a simple and more reliable method of calculation, hoping it will be helpful to you.The formula for calculation is:
First day of the ovulation period = Shortest menstrual cycle days minus 18 days
Last day of the ovulation period = Longest menstrual cycle days minus 11 days
Before using this formula, it is required that the individual observe and record their menstrual cycle for 8 consecutive times to determine the longest and shortest days of their menstrual cycle. The numbers obtained by substituting these values into the formula represent the start and end times of the woman's "ovulation period."
The 5 days before the ovulation day and the 4 days after it, including the ovulation day itself, make up a total of 10 days, which are called the "ovulation period." Because sexual intercourse during the ovulation period increases the likelihood of conception, this period is also referred to as the "fertile period" or "dangerous period."
