Leaking colostrum 19 weeks

Hi all,

Hoping someone can give some advice. I’m pregnant with my second child. I noticed today (19 weeks) I leaked a few drops of clear liquid or colostrum from my left breast.

I did breastfeed my son for almost 12 months so I’m thinking it’s my boobs gearing up for breastfeeding faster?

Is 19 weeks early to see leaky boobs?
