bummed with birth control

So I've been on birth control since I was 13 (10 years ago) for PCOS. I've been on my current pill for a year and a half. Since I've gotten this app I've been conscious of my cycle and symptoms. I've noticed that for the past few months I've been having a full period every 10 days and I've been cramping almost daily for the past month. Is it time to switch pills? This doesn't seem normal.
