Choice A rationale:

The statement "I have some mild discomfort, but it's not too bad" does not indicate a possible complication of ectopic pregnancy.

Ectopic pregnancy is associated with severe abdominal pain, and mild discomfort is not consistent with this condition.

Choice C rationale:

The statement "My nausea and vomiting have improved since yesterday" is also not indicative of a complication of ectopic pregnancy.

Nausea and vomiting can be symptoms of ectopic pregnancy, but improvement in these symptoms would not necessarily suggest a complication.

Choice D rationale:

The statement "I've noticed an increase in fetal movements recently" is not relevant in the context of ectopic pregnancy.

Ectopic pregnancies do not develop into viable pregnancies, so fetal movements should not be expected.

Now, let's move on to the next question.
