Like I said, a woman can have appendicitis and have a surgery to remove the appendix all unknowing she is in the early stages of pregnancy
, and this doesn't disturb the pregnancy
. Your girlfriend's surgery does not sound like they did anything to her uterus at all, or they would not have gone in from the outside but would have gone upwards into the cervix. But why would they have done that, since they knew the problem was a bleeding ovary? They would not.
