Do you gain / lose breast size throughout your cycle?

Hello ladies: at about 1dpo every month, my boobs swell over a full cup size and stay enlarged until my period starts. (Or a more pessimistic way of looking at it: my boobs shrink an entire cup size every time I start a new cycle...) I wouldn't say I am well-endowed, so for me, I personally like the slightly bigger bust. I was commenting on this to my husband and he asked "Does that happen to all women?" To which I responded, "I'm sure we all experience some level of change in breast size throughout cycles, but I don't know about a whole cup size."

So how about it? Do you experience swelling / shrinking? And if so, how much?
