Breakthrough Bleeding and Pill Stacking

I'm on Orthro Tri Cyclen Low. I missed a few pills this month, randomly... always made them up, of course, but I'm now experiencing breakthrough bleeding. I expected it, because of the inconsistency of my pill-taking this month, but my question is, since I'm still taking active pills (which run out early next week) and I'm bleeding... can I skip the placebo week, and stack my pills and Skip the withdrawal bleed? Does this often work? Will it only further mess my body system up, or is it worth a try?
