how many days are in my cycle
On average, a womanâs cycle normally is between 28-32 days, but some women may have much shorter or much longer cycles. Ovulation can be calculated by starting with the first day of the last menstrual period (LMP) or by calculating 12-16 days from the next expected period. Most women ovulate anywhere between Day 11 â Day 21 of their cycle, counting from the first day of the LMP.
