Period Tracking with IUD?

An
Hey ladies!
I've been frustrated lately because I want to track my period and symptoms throughout my whole cycle to get an idea of what I'm experiencing regularly throughout my cycle so I can be more aware of my body. 
How do you guys do it? It's hard to tell when the start/stop date is since I've had mine for almost a year and I hardly bleed if I do bleed. 
Would love some thoughts and advice!
