Am I pregnant?

So my last period was November 28th through December 4th. I was projected to get my period again on the 29th of December. During that timespan my bf and I had unprotected sex twice. He didn’t cum in me but it was precum and as you all know there is Sperm in precum. I haven’t started yet and today is January 8th. I’m about 11 days late. I already took a test and it turned out negative but I don’t know if that’s right because I’m still super late and I have a pretty normal period cycle. Am I pregnant?
