pregnant ? scared to be heartbroken

Learic

My period is 7 days late , and yes I had sex the day glow said I ovulated and 3 days after that also . Part of me thinks period is just late because i tried ONE trial of depo last year but i never took any birth control before anyways i never did it again it’s been over 5 months .my periods were still regular although I would spot for about a week after my period had ended only when i first got off the shot . the doctor said it shouldn’t affect my fertility or cycle because i only took 1 shot then when it ran out i decided that one trial was enough and i didn’t get anymore depo. anyways my last couple periods were regular my period is 7 days late and i don’t really have symptoms of a period or pregnancy . the only changes i’ve had is a increase in CM , cramping , fatigue , and headaches . i’m scared to see a BFN . i’ve just been waiting it out
