How to check if the current page is a “personal activity”-page in buddypress?

I want to modify some general text in my personal-activity page in buddypress.
Does any one know any conditional tag like is_page('activity') things are there for checking this?
the page can be navigated as

member profile page -> activity tab

• Conditional IF statement not returning true even though echo of $user->province is correct
• custom login page redirect to logged in user profile page
• Make specific tag visible only to logged in users in front-end

Thanks in advance 🙂
