plan B effectiveness next day Posted: 02-01-08 00:07am
A couple days ago my g/f and I were
talking about Plan B and how it works
(iono why we were talking about it
lol)...anyways we were both wondering, if
you had sex the day after taking Plan B,
would it still work as an emergency
contraceptive???

No. You shouldn't rely on Plan B as a form
of contraception. If you need birth
control there are many more reliable
methods of birth control options
available.

That's an interesting question. If you
look a few threads up you'll see a thread
about how Plan B works. It delays
ovulation. I'm not sure how long it
delays ovulation, however. You'd have to
make sure it delayed ovulation long enough
so that any sperm deposited in your gf's
body died before ovulation (when the egg
is released). Basically you don't want
her egg and your sperm to meet. Your
sperm can live up to 5 days (I've read
some places that say sperm can live up to
7 days) while it's waiting around for
ovulation, which is when the egg is
released.
So, Plan B would have to delay ovulation
for over a week for it to prevent the egg
from meeting up with the sperm.
Also, the other way Plan B works is to
thicken the mucus surrounding the cervix,
which would hinder the sperm from getting
to the egg. However, I don't know how
long it has that effect, either.
There is also a chance that it could
backfire and enhance the chances of your
girlfriend getting pregnant, because Plan
B is progesterone, and progesterone is the
hormone the body uses to maintain the
uterine lining so it is optimal for a
fertilized egg to implant.
You can call 888-NOT-TO-LATE to ask these
and any other questions you may have
concerning emergency contraception.
Please
note that the purpose of Plan B is to be
used in case your primary method of
contraception failed, like a condom broke,
etc. It is not a primary form of
contraception. The side effects are very,
very unpleasant, and definitely not
something you'd want to experience unless
you were indeed facing an emergency
situation.

So it would make a hostile environment for
sperm?

Yes, it would make the area around the
cervix "hostile" if you mean hard to get
through because the mucus is thickened.

Ok, so did you get your answer? If you

Considering that plan b has a 'success'
rate of something around 89% when taken
within the first 2 days of the 'accident'
- I'd say it is going to go down
drastically as the days progress. So, I'm
going to stick with my original answer
that it isn't going to be very effective
at preventing pregnancy the further away
from the day you take it.
