Help!! I'm scared 🫠

I had unexpected unprotected sex mid june (14.-15.) but he pulled out.. my period is late by 2 days and i have white discharge and tender breasts. But no blood. I know a pregnancy test would give me the answer, but it's sunday and where i live there's no open stores at the moment. I just wanna know if there's a possibility? I've been very stressed this month and my diet hasn't exactly been good either 😕 Can someone calm me down? Any signs I could just be late? or am i pregnant?😭
