2 Day Period when Usually 5 or 6

Hello ladies! So I need your all’s help! Usually when I get my cycle, it starts off brown discharge and ends with brown discharge lasting 5-6 days. This past Friday (Nov.3) I started my period and it was very light pink spotting then eventually got a bit heavier. It was lighter than usual but I have had a lot of clots this time around and faint cramping along with hot flashes and fatigue. I just ended today (Nov.5). This is very unusual for me and was wondering if this could have been a actual period or could I be pregnant? 🤔
