4.5 Understanding Your Cycle
The menstrual cycle can range from 15 to 45 days in length.
Most women and clinicians start with the assumption that
regular cycles of about 28 days long will result in ovulation on
day 14. Although studies
4-7
have shown that only around 30%
of women exhibit this pattern, it is used for the illustration
below.
Menstrual bleeding can last from 2 to 7 days, and the first day
of the menstrual bleed is the first day of the menstrual cycle.
The fertile window is usually up to 8 days in length, and
ovulation generally occurs a day or so before the end of the
fertile window. OvuSense also uses an "ovulation window"
and this lasts from one day before ovulation until 2 days after
ovulation.
