Stressing *HELP* 😭

Shay
So I was on the depo for 2 years and this summer I stopped getting the shot. Well, I had unprotected sex right before my period started (I know it was a dumbass move) and I'm Kind of freaking out. I haven't had my period in over a year so I know the chances of me getting pregnant are slim but I'm scared because I'm in college and my life is going so good right now. I know to be careful now so I've learned my lesson but please help me. What should I do?
