Welcome Harry! LDL is a poor indicator of cardiovascular risk, and according to the best info, Statins only really help people with familial hypercholesterolemia.
I gather cardiologists use Trigs/HDL as a much better indicator of cardiovascular risk and your trigs are nice and low.
LDL might rise for reasons other than diet/cardio risk, eg b/c you have an infection and the body is working hard to repair itself.
More info about these is in the My Low Carb Journey Back to Health pdf which I link to in my signature. You might find the info contained therein of help. Best wishes,
