Pregnant?

I haven't taken a test before you ask but I don't want to get my hopes up so I'm going to ask yalls advice. I have become very tired recently and been noticing a little stomach on me when I've never really had one before. I'm more nauseous than usual but it's not even time for my period yet. My fiance and I have been having unprotected sex for almost a year now and I haven't become pregnant yet. But this time it feels different. What do tall think?
