Should I?

Okay, so I've been on the depo shot the last three months. It ran out on the sixth. While on it I got my period once. Now my period is about 19 days late. I'm not too worried, just want to know others' opinions. Should I take a pregnancy test to rule out that being a possibility? Yes or no?
