Achey breaky boobs

I'm 5+6 today and Oh man...I been sleeping in my maternity bra for a few days now and woke n thought hmm boobs don't hurt much today. Took bra off to shower n a world of pain. I was almost in tears in shower lol Boobs never got this sore with my loss pregnancies. Guess it's a great sign but wowee the pain lol
