I have been taking loestrin 24 fe for 2 years now & have never gotten my period on it. The last brown pill day I had some light bleeding.?

Usually normal. This is a low dose pill and on many low dose pills there is not enough tissue buildup to get a period. There is a newer pill called loloestrin that is only 10 mcg of estrogen that often does the same thing. Your pill has 20 mcg. Estrogen in it.
