Post Partum Boobie shrinkage??

Erin • I'm 22 and engaged to a hard working man, we are extremely excited to welcome our first little family member to this world
I have a really weird question, I was wondering if I am the only one whose boobies got smaller after baby was born?? I used to be a 34D before I was pregnant and not, three months later, I am a 34C. Everyone told me to not get rid of my bras because after the engorgement phase, they would fit me again. Psh. They really don't though lol.
