Absent period

So I’m on a combo birth control called Apri, I’ve been on it before. I always get my period the 3-4th day of the white Inactive pill. This time I’m on the 4th day and I don’t have any sign of my period other than bloating, back pain, cramps, and fatigue. I’m not used to this happening so idk if it’s normal but anyway has anyone ever been through this??
