It's normal to not secrete milk during pregnancy for some women and it is equally normal to have breast secretions especially in the third trimester. Either is not an indication of how much breast milk you would make later. Drinking milk will not produce secretions now or breast milk later.

Thankyou Mrs. Khurana...

milk will start coming after 1-2 days after delivery. as of now ur body is only being prepped for the life within.

Thankyou Mrs Balaji I did't know for this is my first pregnancy....

milk production starts only after delivery so please don't worry about it and just enjoy your pregency
