What is wrong with my cycle this month?!

Heya ladies, I'm currently on CD30 and usually have 28-32 day long cycles. On CD28 i started to get some brown spotting, but only when i wiped. CD29 i got some pinky coloured spotting, but again, only when i wiped. Today on CD30 i have nothing. Does anyone have any idea what could cause this? I never usually spot before AF arrives. I have no cramps or back pain like i usually do before AF arrives. Any advice would be greatly appreciated as i am so confused 🥺
