Reply #42: Unfortunately, you are wrong.

Even though your type is very large, unfortunately, you are
wrong for the definition of "conception" that most of us use.

If the ovum is already present, it can still be fertilized
by the sperm, even in the presence of the "Plan B" hormone.
That's the moment that most folks consider "conception".

In this situation, what happens next is that Plan B prevents
implantation of the fertilized ovum (now called a "zygote")
into the uterine wall. That's why the fundie whackjobs object
to it; they consider the loss of the zygote the destruction
of a human life.

Most thinking people don't draw this equivalence, and realize
that normal women spontaneously abort a large number of
zygotes anyway, but it really doesn't help our cause when
you SHOUT misinformation: Plan B only prevents conception
if ovulation hasn't yet taken place. Otherwise, it prevents
"implantation".
