Sorry if this grosses you out, but dying to know. I'm 22w with a little girl, is this the beginnings of colostrum or should I get it checked out? Comes and goes both nipples, typically comes in the shower or once I'm hot. It's a close up of my nipple and white "goo" but nothing happens if I squeeze. Pic in comment to not offend
