Is there a way to see a history of what I've posted on other peoples Facebook pages?

[Sass]

I not sure if I posted something to my friend page or not. I was about to repost but then I thought what if they deleted it. I dont want to repost if they deleted it. I know I should just ask them but there is a reason why i'd rather not (personal reason). I'd rather leave that option as a last resort. And no what I posted wasnt offensive or anything like that.

There is a way you can access what you have posted.
Go to your timeline, and on the right just under your cover photo, you will see "Activity Log". Click this, and you will be given a list of every thing you have posted, everything you've shrared, everything you've liked and everything you've commented on. If you posted it recently, it should be somewhere in the top of this list. if you see "[Your name] wrote on [Friend's name]'s timeline, x minutes ago" you will know whether it posted or not. If the friend deleted the post, when you click on the link with that entry, it will say something like "The page you requested is unavailable".
I hope this helps solve your problem, best of luck.
