Two Weeks After Explant, from Day One Nipples Sensitive and Smell of Stale Milk?

There looks to be a faint smell of milk from the nipples and a very slight white flaky residue, nothing major at all, Im just courious, the milk ducts look big but the nipples look in good colour and over all everything feels good. They are a little inverted at the moment. Time to see the doctor, or let things settle down?
