When did your milk come in?

When did your milk come in? I’m 20 weeks and a few days and I read it can come in from 16-22 weeks but don’t know how accurate that is.

I have had like zero drainage or any residue on my nips but my nips specifically are sore as hell. They’ve also gotten bigger like a cup size. How do you tell when your milk comes in? I’m confused about the whole process. Like can you start pumping and storing before or do you wait til they’re born.
