Normal on birth control?

My birth control is really fucking with me this month. A week after finishing my period I started breaking out super badly! One day I had some cramps and then started spotting. It’s been a little over a week now and I’m still spotting. Got a little more cramps today and I’ve been feeling sick at night for the past three days. Has this happened to anyone else? I’m on Nora be birth control pills and I’ve been taking them for over a year.
