Is it best milk?

Soccer Mom ⚽️ • Married for 10years to my BFF ❤️, mother of 3 and your typical housewife "busy mom"

I am only 4 DPO from ovulation and in my right breast when I squeeze it I see a little bit just a drop of something come out it looks like milk but isn't it too early??????

Also I have three kids prior so my nipples have already been through the breastfeeding process three times

Can someone please tell me is this milk or something else
