There is new research that shows that PLAN
B does not in fact prevent implantation as
was once thought.
They did certain tests to determine that
the prevention of implantation is
'possible', but not probable.

Well I figured that its main purpose was
to prevent ovulation anyway; and if it did
somehow occasionally prevent implantation,
that the woman was just really lucky.

How It Works Posted: 04-13-07 12:16pm
In my understanding (and this is from my
super-biology course at my all-women's
college) birth control works in three
ways- One way is to prevent ovulation, the
other is to make it nearly impossible for
the sperm to get in by thickening cervical
mucus that it would have to go through,
and the other is to make it impossible for
the fertilized egg to implant in the
uterus if the first two fail. I think that
combined hormone methods do all of this
(estrogen and progestin) but I'm not sure
which specifically does which.
Your estrogen and progesterone levels are
always fluctuating throughout the month,
and the effect of birth control is to
level them off and keep them constant so
that none of the changes are happening
that trigger fertility.
But someone brought up a good point- is
birth control (or MAP) dangerous to the
fetus is you are pregnant and don't know?

There are women that have 'pill babies',
and they babies are perfectly healthy.
OBGYN's state that it is typically
understood that BC does not affect a
fetus.
It is not an abortion, so it does not
'kill' or 'maim' anything.
