If you are having doubts then get a pregnancy test. Having irregular periods can happen but you should definetly make sure. You ight also want to go see a doctor to see what's up with your periods and get tested for STDs.

most likely you are pregnant...but I think you should get a test

if you didnt use any protection and arnt on any form of birth control then yes
its extreemly likley your pregnant
get a pregnancy test or a blood test at the doctors to find out
and next time, be more safe
