Pcos and period

Okay ladies for 2 days I have had clots like this all day I am going threw xl pads within 3 hour. A little back story is I had a baby back in September didn't have a period till end of October and it lasted 3 weeks and I was on bc. Decided to quit the bc and it stopped my period fast forward to this past week I started and it's my first period since October. My doctor gage me provera to get this one started but I have never had huge clots or this heavy of a period ever. I have had pcos since ei had my first almost 8 years ago. Can someone explain to me if this is normal and should I call my doctor???
