Could I get rescinded from UCLA because I got 2 Cs?

I was admitted into UCLA as an Undeclared/Humanities Major. I've had straight As up until junior year. Senior year, I had a lot of personal issues that destroyed my focus and thus resulted in my grades dropping. I currently take 5 AP cles and 1 Honors cl. The cles I got a C in are Honors Physics and AP Calculus AB. I'm hoping that because the subjects I got Cs in had nothing to do with my major, I will be a bit safer. I am working on improving my second semester grades (and I am more emotionally stable now). Does anyone know what could possibly happen to me? =(
