Small amount of lactation?!

My kid is 7 months old, almost 8, and today I jokingly tried to express milk and I had a few sprinkles come out of both breasts!!! My periods not predicted to start for another 5 days, is this a super early pregnancy symptom?! I've also seemed to be more tired the past two days but I'm not sure if that's just my hope getting in the way of my clear thinking. I've also been using opks and each have been getting darker every day when again my periods only 5 days away. HELP, any advice, any stories where you had this happen, ETS would be so helpful.
