I like having boobies.! Before my pregnancy they were just small lol but yea everyone is different
It depends on lots of things. Make sure you have a very supportive bra, and that will help, but sometimes there isn't much you can do to stop it if it will happen
No not necessarily. My friend breastfed and her boobs are still perky. Me on the other hand lol I had a massive supply of milk so my boobs were HUGE. I guess it depends on how big your breasts grow during pregnancy and when your milk comes through
No. Pregnancy itself does.
