It is normal to experience these kinds of changes and pains, it is pain because our breast grow bigger than usual of its sizes, but it is not a lengthen experience.Its duration is short.

It has pain but it is bearable, Imagined within our body there are mechanism that function in accordance to the will of God.Yes it is normal

In reality, if there are changes it hurts, isn't it? and so also the changes of our body it can cause pains because our breast are enlarged, but having this, we can be thankful to be one of the chosen few of all creation, others wanted to become pregnant but it never happen to them.

It happen to our body, just to prepare ourselves to feed the baby with our own blood, and the breastfeeding is the appropriate food for the infant so it can endure sickness/illness that might attack in any time we might not imagined in our life.
Thanks God!
