Hi,
It sounds like you are leaking colostrum and this is 'normal' (Although I haven't & I can't squeeze any out.) I was speaking to a new mum today who had leaked colostrum throughout her pg and her milk didn't come in until 5 days after bubs was born, but she is bf fine now. I don't think if you leak or don't leak colostrum during pg has an effect on your milk supply. If you can squeeze some out my midwife suggested freezing it to feed it to bubs in hospital........
