I always feel a little weird when talking to someone about an upcoming or past appointment, because the phrase I want to use is, "We went to the doctor," or, "I had a doctor's visit," or "At my doctor's appointment." For some reason, swapping in the word midwife sounds weird and catches on my tongue! So now I usually just say, "appointment," without saying doctor OR midwife. But if I slip up and say "doctor" I don't correct myself.
