i would call them asap, then. you should have received a little book (blue if you had a boy, pink if you had a girl)... at the back, they usually have a place to write the appts.
i had two complicated pregnancies seen to by the high risk team at QMH. both kids were delivered via c-section. i had to go the day after discharge to have my stitches removed and for them to check out the baby. i'm not sure what the drill is if you have simple, natural deliveries without any complications.
i would call them RIGHT NOW.
good luck!
