Breasts several months after miscarriage (TMI)

I had a miscarriage at the of July and my boobs and nipples/areola got really big with the pregnancy. Within a few days to a week after I miscarried, my boobs/nipples went back to normal, but I have noticed that every now and then my areola seem slightly bigger than normal. This morning my areolas were HUGE again! Like bigger than a quarter. Usually, they are pretty tiny. They're not sore and I don't have any pregnancy symptoms (really doubt I'm pregnant). Has anyone experienced anything like this after a miscarriage?
