If a woman is already pregnant a morning
after pill is unlikely to have any effect
on the foetus/embryo.
If you got pregnant while on birth control
again it isn't likely to harm the growing
child, but don't rule out the possibility
of birth defects. Same as if you started
birth control if you were already
pregnant.
I believe in .U.S that before you get
birth control (pills/shot) you have an
orientation and exam if it is your first
time on birth control. I understand they
will ask if there is any chance you could
be pregnant and test for it.
Scaredbaka I am going to post you get
another link to a site found by
hotasfrick, if you care to read any of it
it does answer most of your concerns.
