pregnancy scare

hi so partner and I had impulse unprotected sex and we both regret it and don’t know what to do

i (m) penetrated her (f) with no contraceptive on and did stuff for like two minutes. we stopped after we got out of the haze but I felt pretty close to orgasm so I’m worried about precum pregnancy.

What are the chances? And what do we do since we are not from a country where Plan B is available?
