Breast pain during pregnancy

I’ve been very restless lately, one amongst the million pregnancy symptoms. I normally sleep on my side and not a huge fan of sleeping on my back or stomach.. only ladies know what I mean by this; so when you are on your side naturally your boobs just kinda push together... so when I try sleeping on my side and my boobs push together it hurts so bad and I’m only 9 weeks along.. anyone else experience this, any tips to ease the pain a bit? (No I don’t wear a bra to sleep, should I??)
