could I be pregnant

I have been getting sick all the time I feel like I can't eat I'm never hungry iv been bloated and gassy tired all the time. I just feel like crap I got my period 2 weeks ago it was not heavy like it usually is. I used about two tampons during my whole period it was over.  I had sex a few times the week b4 my period. Should I make a appointment with my dr to check . Or maybe I'm just coming down with something
