9 DPO Leaky Boob

I am 9 days DPO and had cramping from 5-8 DPO and today no cramping but my left boob leaked a little today and I can get a little liquid out of it if I try. I breastfed my daughter until she was one and she is now 17 months old. I haven't leaked or been able to get any liquid for at least 4 months now. Any ladies have leaky boobs before they found out they were expecting baby #2??
