What happens to big breasts after child birth?😹🙄

So I'm currently 35 weeks pregnant, pre pregnancy I was about a C cup now I'm full grown DDD & they won't stop growing... i know it might sound funny but it scares me, my boobs are literally bigger then my bump, i have to lift them up just so I can breath... at night time I switch positions not because of my belly but because of my freakishly big boobs 😩😹

After all I totally understand that having a baby comes with all sort of changes, I don't hate my body and I would never do something to hurt myself or my baby, it's just that it can get really uncomfortable, and... yeah those who can relate know the deal, I'm really looking forward to breastfeed & would like some advice from women in the same situation eg: do they keep growing, does it hurt more etc just curious about how women with the same experience dealt with it. ❤️️❤️️
