What does this all mean?

So I'm supposed to get my period the day after tomorrow and I've been having slight cramping but not like my normal period cramps. My boobs have been kinda sore too they kinda feel like they are a little bigger but I'm not sure. I've been super tired most days the occasionally I'll have bursts of energy to get stuff done. I've been more moody than normal and I get dizzy and some headaches. My taste buds are changing and I can smell a lot more It seems like. Me and my hubby haven't been using any protection and we did have sex while I ovulated according to Glows prediction. What could this all mean???
