Click here to find out when you are most
likely to
get pregnant
This interactive tool estimates your peak
fertility period, also known as your "fertile
window." This is when you are most likely to
become pregnant.
To find your peak
fertility period, the tool calculates the
day you are most likely to ovulate by using the
date of your last menstrual period and the
typical length of your menstrual cycle.
A woman is usually able to get pregnant for
about 5 days each month, when ovulation occurs.
On average, ovulation occurs 12 to 16 days
before the menstrual period begins. The key to
becoming pregnant is determining when ovulation
will occur. Because sperm can live for 3 to 5
days in a woman's reproductive tract, it is
possible to become pregnant if intercourse
occurs several days before ovulation. This tool
should not be used to prevent pregnancy.
Your
menstrual cycle begins with the first day
your period starts and ends the day before your
next period starts. If you do not know the
number of days in your menstrual cycle, use 28
days, which is the average length of a menstrual
cycle. If you want to determine the length of
your cycle, use a calendar to track it. Some
women have longer or shorter cycles.
While women usually ovulate at day 15, it's also
normal to ovulate well before or after the
15-day mark. This calculator is therefore meant
to give you a rough estimate.
