Paranoid?

I was seeing a guy for about a month. I stopped taking the pill prior to meeting him due to other health issues. Condones weren't working for us so we decided to try vcf. Vaginal contraceptive film. He also pulled out.  But things went bad and he vanished making me wonder what kind of guy he was.  Now I'm paranoid can I be pregnant? What are the chances. Also been a little itchy down there but it could be from shaving... Am I paranoid?
