One breast has started growing much larger than the other

I’m 54 and in the early stages of perimenopause. Over the last few months (3 maybe?) my left breast has been growing larger and larger. At this point, it’s so noticeable because my shirts always fit off center now. I don’t wear tight shirts anyway but this has caused me to start buying bigger shirts so it’s not as obvious. There aren’t any lumps to speak of. And no pain at all. Does anyone have any ideas why this might be happening? 

I breastfed all 8 of my children and because my left nipple is inverted, I always let that one dry out and only nursed on my right side. I only used both when I had twins. I don’t know if this has anything to do with it or not? 

I’m scheduled for my annual exam in January and I plan to bring it up with him. I actually expect he’ll say something first because it has become so much bigger now. 

Does anybody have any ideas??

BOTH of my breast have become so much larger its ridiculous ! I never breast feed , I do have 8 children though!

Hi,

Both of my breast have grown too. And also very tender!

I had the mirena coil put in October to slow my bleeding down and thought maybe it could be connected?

I looked up breast pain in menopause and this can happen too. Crazy!
