I'm 12 days late on my period!! Can I be pregnant?

My last period was June 2nd and lasted the full week. It came when expected I had sex two days before that. The condom fell off and we realized it late but I still got it. I haven't done anything since and this month I'm late. I've had no symthoms but occasional like bumping in my stomach but I think it's just my head! Help. I took a pregnancy test 2 days after it was due and it was negative
