Yes, it absolutely does, and it can feel so heavy and tender. I used to worry if this soreness was normal, but it's just the early hormones doing their work.
Babe, don't stress too much if they feel huge or tender all of a sudden. It's totally normal, just switch to some super soft cotton sports bras for now.
Mine literally grew a whole cup size in just the first month and I was so worried about stretch marks! But my doctor said it's totally normal, just use a good moisturizer.
According to my tracker app, breast changes and tenderness are actually among the very first signs of pregnancy! Hormones like progesterone increase the blood flow there.
I panicked when my regular bras suddenly stopped fitting by week 6! But my gynac said it's totally normal as breast tissues prepare for milk production.
It definitely does increase and feel quite sore due to the hormones. It can be uncomfortable, but please take gentle care of yourself during these sensitive weeks.
