Am I Pregnant?

Lately I’ve been getting irritated very quickly, I’ve been emotional, I’ve been having an awful and strange stomach pain, I’ve been eating more than usual, using the restroom more frequently, and my period came a week and a half early which has never happened before, it was a different color than normal and it only lasted 3 days. My boyfriend has never came inside of me but we are sexually active without protection... could I be pregnant?
