Sore itchy boobs

I'm just full of questions today!!! I've felt so different this month and have had a ton of symptoms. Exhaustion, sore boobs, headaches, etc. However I started my period on Saturday. It has been very light and has been pretty much brown with a few spots of bright red blood here and there. My boobs have been sore and sooooo itchy. I don't know what to think about this. Any thoughts?
