Okay so yesterday I uploaded a photo of what I thought was a vvvvfl. I am now 11DPO and AF is due 4th July I have just got in from work and after experiencing backache (due to a trapped nerve I think) and cramps all day including dizziness and extreme tiredness I went to toilet, but when I wiped it looked like really light pink blood. I'm not sure whether my period has come early or whether this is something else. My blood is never pink it is always either brown or dark red. Please help!
