Any ideas?

So I'm due a period 9th tomorrow, on the 5th I started spotting pale pink didt think anything of it at the time just assumed period day r two early no Biggie! stuck a pad on go to bed ! Next morning I normally would wake up to heavy bleeding it's my normal but nothing on pad ! Fast forward a few hours pale pink spotting again then nothing then today tiny light brown spotting like it's barley there has anyone had similar and cycle sorted it self out come the actual day your period is due? I don't normally spot days before hand
