23 weeks and shrinking breasts

Hello all. I am 23 weeks pregnant and since about week 10, my breasts have increased tremendously in size. But then today, all of a sudden, it seemed like they deflated just a bit (not greatly, but enough to where they looked different). I can still feel the baby kicking, and maybe I am just being overly anxious, but has anyone else experienced these changes.?

I am getting worried now. Does anyone have any input? 

It could be water retention, but if you are worried call your doctor.

That's normal. Mine are doing the same thing. Just like they swell before a period in some people, they do the same during pregnancy. It's water retention and hormones. As long as baby is still kicking and nothing else is out of the ordinary...I wouldn't be concerned.

I think they are just fuller some days than others. Mine still fall out of my C- cup though. I started an A!!! LOL!

Yeah, I ended up calling a lactation specialist and she said that breasts will go trhough all sorts of changes--increase/decrease in size, change shape...etc.  I fall out of a C cup too now, and I started at barely a B. Thanks for the response.
