Perioddd

So usually my cycles are about 29-31 days long. In October, I had a 34 day cycle. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, I should get my period on November 13th, 30 days from the last time I got it. Will I get it then or will I get it 4 days after expected since I had a 34 day cycle last month??
