911!!!! PLS HELP

hi ladies💘
i've been on the pill for two years now, i skipped my last month because i've been moving to a different city and my pharmacy kept failing to refill the prescription. 
i am sexually active, i haven't been except twice since i have stopped taking the pill,
the problem is, i haven't had my period for this month, i read that my period could skip two or three months due to resetting itself from the  birthcontrol.
i've been SUPER snappy and breaking out and easily frustrated. is this all a cause of the horomones imbalance?
Should i still be worried??
& does anyone know how to induce a period😂
