Am I pregnant?

I know this is stupid and possibly impossible, but me and my partner had unprotected sex the day before I was due my period 2 weeks ago. I then started my period a week late which has never happened before, and now I have came off my period yesterday, I have been extremely bloated today and have been off eating for the past week. 2 symptoms I had when I was pregnant with my daughter. Could I possibly be pregnant?!?!?!?
