Should I be concerned?

It should show you when, on mine it does. I got concerned when mine looked at that or those kinds of things, it was a psub to me. It was enjoying other women. You can also see ads that were looked at, videos that were watched, etc.
I hope you do not have to be concerened. Did you have a gut feeling and that is why you looked?

 

Here it was Youtube that was even worse.

 

Usually when we get comfortable and do not check that is when they are at it again. Hopefully not your So and yes there is but I look on my main computer vs my phone as I can navigate better with checking on it. Here the dumbass used my Facebook account. He did not know it saved it all. He had used it before too but got comfortable and dumb.

 

It all should be in the activity log, under Filters, there is a list to click what on the list under Filters in Activity Log you want to see what was viewed, like or commented on.
