HElP 😐

Hey I am not due on till Saturday 11th June 2016
Last night 8 June 2016  before I was going to bed I went to the toilet to find light brown blood I'm not sure how to exsplain so will post pics below 
This morning I wake up thinking I may be on and nothing I have slight cramps in my belly and have done since I woke up at 6:30 this morning 
Dose anyone know what this could be period not due for another 2 days I'm so confused
