20ml colostrum @ 37 weeks

Received my breast pump recently and tried it out for the first time today, about 20 mins on both sides at the same time. I ended up producing about 10ml from each breast! I'm amazed I can do this because I haven't leaked at all throughout pregnancy. Is this normal? Could this volume mean I'm going into labor soon? Currently 37 weeks and 2 days, 3cm dilated, 75%effaced, head down and "right there", minimal contractions/cramps so far.
