Contraception
What
is Emergency Contraception?
Emergency
contraception is used
after unprotected
sex to prevent
pregnancy. It is
sometimes called
EC or "the morning after
pill."
EC works best if you
use it right away.
It can be used
for up to five days after
sex. Use EC if:
You
think your birth control failed.
You
didn't use contraception.
You
were forced to
have sex.
There
are some other
options for emergency contraception. The Copper T IUD can
be used as EC
for up to 5 days after
unprotected
sex. Taking several birth
control pills at
one time may also
work.
Only certain brands of birth
control pills can
be taken in
large doses as EC.
Talk with a health
care professional if you
want to use birth
control pills as EC.
How
effective is emergency
contraception?
The
sooner you
take EC, the better.
EC can be taken
up to five days (120 hours)
after unprotected
sex.
How
does emergency contraception work?
The
hormones in the pills may
do several things
to prevent pregnancy,
including:
Stopping your ovaries
from releasing eggs.
Causing cervical mucus to thicken.
This blocks the opening to your
uterus so sperm can't reach
an egg.
Making the lining
of your uterus
thin.
This prevents an egg
from attaching
to the uterus.
If
you are already
pregnant, EC will
not work. If you
do not get your
period
within a month
of taking EC, you
should take a pregnancy
test.
What
are the benefits of using
emergency
contraception?
EC
is very safe.
EC
can prevent pregnancy after sex. It gives you
a second chance to avoid pregnancy
after an unprotected
sexual experience
or if you had
a problem
using your regular method of birth control.
What
are the downsides of using
emergency
contraception?
EC
does not protect
against sexually
transmitted infections (STIs).
EC
will not work
if you are already
pregnant.
EC
might make you feel dizzy,
tired, or feel
like throwing
up.
EC
can cause stomach
pain,
sore breasts, irregular
bleeding, or headaches.
EC is less effective at preventing pregnancy than some other birth control methods. It should not be used as your regular form of birth control. It can cause irregular periods with frequent use.
