How Can Breakthrough Bleeding Can Be Stopped?

I am on the pill yasmine. I carried on about 4 packs of the pills so therefore skipping my withdrawel bleeding. I then experienced breakthrough bleeding because of this. I had my withdrawel bleeding this month to sort it out. I am going on holiday in 3 weeks time and am due on my withdrawel period that week, so i am going to carry on packs again to skip that. Will i get breakthrough bleeding again? and is there any way of stopping it?
