Birth control patch and irregular periods

I have been on these patches consistently for over a year. I am still dealing with breakthrough bleeding with the same excruciating and heavy periods. My periods also come every two weeks, then I end up bleeding for two weeks. It comes every month on my third patch week, so I feel as though I am wasting a fresh patch. I tried skipping periods, and it still does not work; I still bleed. Also, they suck at sticking to the skin. It's a horror trying to shower with the patch on because it will come off. After a shower, I'm more focused on trying to get it to stick back onto my skin. And it does move across the skin, and leaves square prints on my skin, due to the adhesive. I would not recommend these patches to anybody who wants to shower regularly, or do water activities while trying to manage periods and prevent pregnancy. I have made an appointment with my doctor, to change my birth control method.
