Help!

Okay so I'm currently 2 days late. I know that's not much but I'm pretty worried. I am having all the symptoms of being on my period (fatigue, mood swings, slight cramping, some cravings) but I'm not bleeding. I don't know if maybe my period is just late or if I need to take a pregnancy test. My fiancé isn't as worried as I am but I know my body and it's not normal for me to be late. Help!
