Leakage? Help please

I’ve been having some leakage. I never got this before when I found out I was pregnant with my son. My period is due today and I took a test and it may have had a vvvvvfl I breastfed my son for a couple months after he was born but it’s been over a year that I have breastfed. Would this be happening because I might be pregnant? Or will this always happen since I’ve had a baby?
