Weird period??

So I can't remember if I started Monday or tuesday of last week.. My calender says I only had my period for two days.. But I think I really had it for three.. Anyways it was still short but kinda heavy. Then when my period stopped I had Brown discharge for three days. So I am kinda confused. I want to wait but then again I want to know if I am pregnant. The only weird thing I am going through is weird smells.. And it's overwhelming. Like some foods don't even smell normal to me. Like I was cooking Ramon noodles and almost barfed over the smell. It just stunk and didn't smell usual. And neither did my step daughters cooking. So you think I should test? Or maybe wait? I really don't want to let myself down.
