Should you pump after abortion?

I've started expressing some liquid from my breasts after having my abortion 2 weeks ago. I've been trying to keep anything from stimulating my breasts, but today they are very sore and feel similar to how it would feel when I was really engorged during nursing, but without the actual physical engorgement.

I'm worried about a block, but I'm also worried this will just make my body continue to produce milk.

any advice?
