Just got off depo but took a plan b and don’t know how delayed my period may be.

I’ve only had two periods coming off depo but they weren’t regular, a week before my third period I took a plan b and I haven’t gotten a period since. It’s been 14 days passed my last period; should I be worried and take a test? We always use condoms and on the rare occasion that the condom breaks I take a plan b. In this case he didn’t cum at all but it broke so I ended up taking a plan b just be safe since I hadn’t taken one since last year. Idk if the hormones from depo could still be delaying my periods or making them irregular or if its a mix of both of them, I know plan b should only delay by a week if it is delayed.. thanks for any help :/
