Thank you for your response kia. I just
did a little research on the internet and
found out that "during the first two weeks
of development, the embryo is thought to
be resistant to any teratogenic effects of
drugs". I feel so much better now.
Hopefully this is helpful to other women
in this forum.
Below is what I found:
a medicine may have more than one harmful
effect on the developing baby depending on
the timing of exposure. During the
first two weeks of development from
conception to the first missed period, the
embryo is thought to be resistant to any
teratogenic effects of medicines. The
critical period of embryonic development
when the organ systems develop starts at
about 17days post-conception and is
complete by 60-70 days. Exposure to
certain medicines during this period
(17-70 days) can cause major birth
defects. In general, exposure to
medicines beyond 70 days post-conception
is not associated with the induction of
major birth defects.
