missed depo

Hey guys so I took one shot of the depo may 10th and have been TTC since beginning of august.. AF was supposed to be here yesterday and she is NEVER late (still had my period on the depo)...took hpt this morning and nothing..but having sore boobs bad nausea super emotional can smell anything and my appetite comes and goes...ugh what should I do? When I was on depo before I never had any of these issues. Helppp !!!  should I wait longer to test or wait until AF is fashionably late ?
