Patient's question:
I got my period on May 21st and it ended on the 25th. My period is very regular, occurring every 28 days. I am currently trying to conceive and find it difficult to determine my safe days and ovulation period. I really want to have a baby.What kind of help do I need: How many days after my period ends is the safe period?
Doctor's answer:
The formula for calculating the ovulation period is as follows:Ovulation period, first day = Shortest menstrual cycle days - 18 days
Ovulation period, last day = Longest menstrual cycle days - 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 above formula represent the start and end times of your "ovulation period."
(The calculation of the menstrual cycle is from the first day of this menstruation to the first day of the next menstruation.)
