Leaked milk at 19weeks pregnant

Hi everyone alittle tmi but I am little concerned, this morning me and my husband where intimate and I was on top and he was stimulating my breast I opened my eyes and seen a lot of milk/ colostrum on his chest and going down his neck from one of my breast and it completely turned me off because I was shocked at seeing colostrum so early on this is my 6th pregnancy and I have never had any milk or colostrum leak till after birth . Is this normal ? Has this happen to anyone else before ? I am alittle worried because I read it can bring on labor if I have colostrum leaking please correct me if I’m wrong or if you know anything about this thank you in advance.
