Are you trying to ask something along the lines of: "if fluid (milk) is leaking from my breasts, am I pregnant?"
Colostrum (pre-milk) will leak from the breasts of a pregnant women and can occur anywhere from late in the first trimester onwards - it is not milk as GRose pointed out. If you think you might be pregnant, take a test. If it is negative, you need to see a doctor to find out what the fluid is that you are leaking as it could be any number of things including an infection.
your question is a little confusing....
If you are pregnant you may leak some colostrum during your pregnancy but your actual milk supply does not come in until a couple days after that baby is born.
what?
are you pregnant when you have breast milk cominig before you give birth.
well if you are pregnant than you would be giving birth yes!
if you have milk leaking from your breast that does not alway mean your pregnant no.
not quite sure what your asking
