Boobs

I know this may come off selfish but is it wrong that I'm already worrying about what my boobs will look like after I have this baby and breastfeed. I liked my boobs before, they were a good size A cup and they were perky. I'm so afraid that I won't have anything when I'm done and that I'll look like a boy. My mom had 5 kids and doesn't have any boobs left. I think I'm just ranting but it's something that's been on my mind.
