Calendar Based Method!
If
you are sexually active, you must take precautions to guard against unwanted
pregnancies and sexually transmitted diseases. For unmarried women who engage
in multiple partners, it is still best to use a barrier method. However, for
women who are in long term monogamous relationships, there are other
contraceptive methods available.
Calendar-based
methods are various methods of estimating a woman's likelihood
of fertility, based on a record of the length of previous menstrual
cycles. Various methods are known as the Knaus–Ogino Method and
the Rhythm Method. The Standard Days Method is also considered a
calendar-based method, because when using it, a woman tracks the days of her
menstrual cycle without observing her physical fertility signs.
To
begin the calendar method of birth control, a woman must mark the first day of
each menstrual cycle on a calendar. This first day is signified by the shedding
of the uterine lining when most women experience bleeding.
According to Planned Parenthood, ovulation can
be predicted after eight cycles. The calculation consists of counting the
number of days in each cycle, identifying the shortest and the longest cycles,
and then computing the first and last fertile day in the cycle.
Based on the calendar method a woman should
avoid intercourse or use a back up method of birth control between the first
and last day of predicted fertility. This is also the best time to have
unprotected sex when trying to conceive a child, per Planned Parenthood.
Here is an example:
Predicting your first fertile day. If your shortest cycle
is 26 days long, subtract 18 from 26. That leaves 8. If day one was the fourth
day of the month, the day you will mark X will be the 11th. That's the first
day you're likely to be fertile. So on that day, you should start abstaining
from sex or start using a cervical cap, condom, diaphragm, or female
condom.
Predicting your last fertile day. If your longest cycle
is 30 days, subtract 11 from 30. That leaves 19. If day one was the fourth day
of the month, the day you will mark X will be the 22nd. That's the last day
you're likely to be fertile during your current cycle. So you may start to have
unprotected vaginal intercourse after that day.
In
this example, the 11th through the 22nd are unsafe days. All the others are
safe days.
For
some people specially men it's a difficult but effective way to keep track and
be alert, another very effective and easy way is to use TECHNOLOGY there are so
many apps on the market that uses the calendar method and let women to be in
control of all this easier.
Also
there are apps for couples like couplecare
an app that recommended for couples that let the woman to keep track of her
cycle like many other apps but with the advantage of sharing it with her
partner letting both keep track and have an extra secure relationship
