i think Hazey amber r completely right , but im sure in the same time .. she loved u , and for that she dont want you to suffer during her childbirth.
when she is ok after birth , asked her about that , and dont judge her for one mistake.. may be u will learn from her some thing u dont touch
be happy of her brith and her baby , dont make this matter spoil ur happiness of the new baby.. be optimistic
god bless all of u
