Am I pregnant?

My cycle is on the long side, like 30 days plus
On day 4 of my period I had unprotected sex and he didn't pull out, am I going to get pregnant? 
I'm on day 6 now.
I have not taken any tests as I think it's too early.
I thought it was impossible because the app doesn't show a % likelihood and now I'm panicking because I read online sperm can live 6 days. My boyfriend is probably taking a job in China- I live in Canada. So I can't really handle the prospect of it.
