I suppose I should know this, but was my BC treated as TNBC?

After learning so much from this board, I think i may have been a bit naive with my diagnosis. My ER was 93% +, PR was 4% + and Her2-. 1 malignant tumor at 2.3 cm, 1 node positive, tumor grade 3. They put me into chemo almost immediately. Was I treated as TNBC?
