Has somebody been on my facebook account? is somebody trying to hack me?

[higur]

I was recently going through my facebook security, and went through my "active sessions" tab, since I haven't been through it in a while. Everything looked normal, just a few were open (such as the one on my phone, and desktop) but there was one active session that had been active since the 9th of july all the way from New Brunswick (I live in British Columbia, quite a long way away) on an ipad. I do not own an ipad, however, I have accessed my account and it is quite possible that I could of forgotten to sign out. But it said that my account was being accessed from new brunswick? this makes no sense to me.

My account has had nothing bad done to it at all, but sometimes randomly I log out of my account for no reason, which is a technical glitch I hear, for the most part.

Could this be a glitch on facebook's part? or is somebody lurking on my account or is this simply some sort of software that has put itself on my account? please help! 5 stars best answer!

(Yes I have taken all security measures, password change and all)
It said "last accesed" 9th of july i believe, or it could of been "access started on 9th of july".
