Quick long question

It is a little long but please read if you want to question

Ok so my periods are normally heavy ish medium flow with cramps that require Motrin and hot water bottle.

This past period started on time was on lighter then my normal cramps lasted two days were mild only took one Motrin first day. And still lasted my normal four days.

Now I get sore tender bbs from ovulation to period start

But it is almost my fertile week and my left bbs is being wired I get kinda a pulling sensation once in a while could this be caused from me shovelling snow? Or is this hormones related to perimenopause, or something else. Mind you I just had a boob exam in Nov was all good so no lumps tumours or anything .

My right is doing the same but lighter much less noticeable.

I felt ok up till two days ago.
