Post partum bleeding

So I’m 3 weeks PP and I thought I was almost done bleeding since it’s been very light. But last night I noticed my pad was bright red and I had some small clotting along with heavier bleeding. Today it was a little more blood and clotting. I’m more sore than I was just a couple days ago. I do have internal stitches and a 2nd degree tear. I also hemorrhaged and had to have two blood transfusions. Is the sudden bleeding normal since delivery was rough or has anyone else been through something similar? I looked at my discharge papers but all it said was if I filled a pad in an hour to go to the ER, but I’m not filling the pad. My doctors office was closed yesterday and today and I really don’t want to make an unnecessary trip to the hospital. I do plan on calling the doctor tomorrow.
