Is Facebook Ok?

On my facebook, i sent several friend requests but they havent shown up on my Activity Log I know they are still pending as they all show up on my list of friend requests and on the individual accounts it says 'friend request sent' Yet none of them appear on my activity log Im worried what if i am under surveillance and someone has stolwn that information to spy on me? Bit paranoid maybe but i am worried as i dont have this problem on my other facebook account
