Not necessarily when I was pregnant my milk started leaking out at 20 weeks and I carried him full term... It just means that your milk gland are full and they are releasing some so that it can continue to replenish your milk
You are lactating... Your body is sending signals letting itself know that your baby is going to need milk. Its just producing milk... If you want to you can buy a breast pump and pump your milk before your baby enters the world. Freeze it or refrigerate it. Breast milk does not last as long as regular milk.
