What jespah said is true. It can hardly be formed an accusation on this situation. I will try to explain the medical reasons;
First, there was something wrong going with that pregnancy. With those high levels of HCG and the difficulty to visualize a correctly growing embryo inmediatedly will ring the bells of any cautious Gynecologist.
Second, ectopic pregnancy is a surgical emergency, the decisions must be made fast.The reaction was appropiate to the suspicion. Although the tube was clean the clinical alghoritm was followed.
