Advice

I need some help to know if this could just be in my head or not... I had a normal period last month around eight or nine days after my period ended I had spotting for two days literally tiny spots of blood when I wiped a couple of times then some very light pink discharge, almost two weeks ago now my breasts are sore, I can't stay awake in the evenings and today I got very light headed, I've been through a very bad week last week so not sure whether it's all catching up on me now or could I possibly be pregnant? Due my period this Friday! Xx
