Depo shot

Julia • 20 & in love
So I got the depo shot October 27th, the day before I was supposed to get my period. They tested to see if I was pregnant (which I wasn't). I waited a week before having unprotected sex. It's been 49 days since I got my last period. Should I take a pregnancy test? I know some girls stop bleeding after the shot so that could just be what it is. Thoughts?
