am I pregnant ?

My period lasted 5 days, I had unprotected sex 2 days after my period ended. He didn't ejaculate in me however I'm worried that I might be pregnant. I've been really anxious and stressed out because of this and I'm not sure if my mind is playing tricks on me. I feel a vibrating feeling on my stomach and I was wondering if this is a pregnancy symptom. It's been a week since I had sex. Can someone please help me.
