Sore boobs come and go?

Sheena • My fiancé and I have been together for 8yrs. We just bought our 1st house. We have been Happily Married for 4 months:)
Is it normal to have sore swollen breast and then they go away for a little bit? My breast have been sore this whole time and now they just went down for some reason. It's really scaring me. Anyone else experiencing this?
