Help! Pt 2

So, Last Week, I Had A Spot Of Blood On My Toilet Paper. Not Much. Then No More After That. Then About 2 Days Ago, I Had Light Pink Spotting On My Toilet Paper, Then Again, No More After That. I Am Due To Start Today But No Signs Of It. My Nipples Have Been Sore, Ive Been Extremely Tired && Only Wanting Pizza && Wings. Normally, I Hate Wings. Ive Also Been Extremely Emotional. What Do I Do.?
