Could I be pregnant?

I had unprotected sex twice about 2 weeks ago, he pulled out but I know this isn’t a full proof method (16/17th of November) and my period wasn’t due to come until around the 12th of December but I’ve been bleeding today (4th of December) but I’m scared as my period has never been early!! I was worried this wasn’t my period but actually something to do with me being pregnant lol!? We’ve since used condoms every time:)
