dose...did I do the right thing

I forgot to take my pill for three days. I was spotting and thought.....maybe I should "catch up" by taking all three at the same time today. I am not sure if I did the right thing. Should I have just had my period, I am in the last week of the pack anyway. But my doctor doesn't want me to have a period because of my past endometriosis...with three surgery's. Please help anyone. Did I do the right thing? Thanks.
