Random breastmilk leaking 6 months after weaning????

Va

Hi there, I had stopped nursing my daughter in January. A full 17 months!

But now, during these last few weeks I’ve noticed I keep having some milk leak randomly. I’ve checked and it’s definitely white milk- not clear like colestrum. I had been completely dry for months and wasn’t having any leaking up till now.

Is it normal to randomly start having leaking MONTHS after not having any??? I don’t think I’m pregnant but will know for sure next week. Also don’t know that pregnancy would bring on milk leaking again after so long?
