I'm sorry it's not exciting but I would really like help

About 9dpo (normal 15 day luteal phase) I started cramping. 2 days later (5 days early) af showed up. It was light flow for 3 days then spotting for 2. A week later I started spotting again. It got a little heavier but I'm not even filling a pantyliner. It's mostly when I use the bathroom. This is day 5 of that. Has anyone had this happen or have any insight? I just want to know what my body is doing...
