Understanding ovulation is an important step to getting pregnant. Ovulation occurs once a month when a mature egg is released from the fallopian tube and is ready for fertilization. During ovulation, the lining of the uterus is thick in preparation, which is then shed if conception doesn’t occur. Most women have a monthly cycle between 28 and 32 days, and ovulation usually occurs between day 11 and day 21, counting from the first day of the last period.
How to use a Fertility Calendar
Using a fertility calendar, you can track the length of your monthly cycle to determine when you will be fertile. Using a regular calendar, circle the first day of your period and count the number of days of your cycle, including the first day. Doing this for at least 8 cycles will give you an accurate measurement for understanding ovulation. To determine the first fertile day in your current cycle, look for the shortest cycle you’ve kept a record of. Subtract 18 from the total number of days and count forward that number of days from Day One of your current cycle. This is your first fertile day of the current cycle.
