Breast leaking

Nakita • 30 years old, Married Baby 1- June 2015, Baby 2- October 2016, Baby 3- March 2018! Baby 4 October 2019

So my youngest is just about 1 year. I stopped breastfeeding at 9 months with him as suggested by my dr(hes my 3rd baby). My milk dried up almost instantly. Well I'm around 5 weeks pregnant and and my boobd are already leaking again! Anyone experience this?
