Swollen breasts post period???

I am always consistent each month..my symptoms of swollen and achy breasts begin about a week before my period and ends slowly after my period begins...all my pre period signals were the same this month, however post period is doing something I've never experienced.

After my period ended, I spotted for 2 days. (Not usual for me). My breasts then started to swell again. The pain is on both outer parts of my breasts, and is to the point where I cannot sleep on my sides(worst great pain I've had). I also have been feeling very moody, a little nauseous and sleepy during the day.

My period ended 5 days ago and I am experiencing all this...any one else experience this/have advice?? HELP PLEASE😫
