not so typical topic?

 Me and my soon to be husband (November 5th 2016) haven't been TTC nor have we been preventing it either. I'm now 56 days late and on day 94 of my cycle. I've taken plenty of pregnancy test and they're all negative. I'm not on birth control nor have I ever been. My periods are pretty normal. What could be the problem?
