20 day cycle??

Ra

All month long I have been cramping since Ovulation, then this morning they were unbearable so took Tylenol, then A/f started about 30 minutes later, 9 days early. Is this normal? last month it was a week late. . 😢😢 I'm in the process of getting insurance, just want to know if it's normal tho have wacky periods in your 30s. . . I've been normal my whole life, from when I started at 17 until 32.
