Yes, in fact, I was producing breast milk two months before my second daughter was born. It is not unusual for there to be milk in the weeks before delivery; but, it is very unusual for there to be milk months before the delivery.
It turned that there was nothing physically wrong with either myself or my pregnancy; but, I did attend a doctor just to make sure.
So, while wearing breast pads for a time before giving birth may be a pain, I'm sure you, your pregnancy and your baby will be fine. However, it never hurts to be cautious, so go to your doctor for a checkup and to let him know what is happening.
