My period starts before the sugar pills every month. if i take two pills on those spotting days will it prevent that from happening or make it worse?

Probably: you will waste some pills but it should work. there are 24 day BCPs that may work for you as well.

Talk to your doc: Breakthrough bleeding is very common with low dose birth control. I would speak to your health care professional about other choices in pills and other methods that are available. I would not change your dosing without advice
