Help!! Is this all normal?

So I just got off my period a couple days ago, but it was shorter and lighter than normal. Usually it lasts 6 days and this time it lasted 4 and a half almost 5 days

The bleeding did fill tampons on day 2, so I’m assuming it was my period

It also came on the time I expected it

I haven’t been sexually active in a couple years so I don’t think pregnancy is an option

Usually after my period ends my breasts stop being sore from the pms before my period but mine stayed a little sore after this lighter period

Is this normal? For my periods to be weird sometimes? I have no idea what to think
