HELP!!

Christa
Period isnt due for 8 days. I Should've ovulated around the 21 22. For the past week my boobs have been extremely sore,( usually not sore until the week of my period never a whole 2 weeks and they never hurt this bad before) I have been nauseous and just feel bloated and for the last 2 days I have felt like im getting my period. Could I be pregnant or just getting my period?
