If you're looking for new replies to your posts, that is still under unread posts. If you don't see either of those areas, you probably clicked on the arrow next to main menu. It should be pointing up if you want to see the account info. If it's pointing down, just click on it and you'll see your photo, hello message, etc.
You can also go into your profile and see all of your posts.
I hope this helps! If not, let me know and I'll see what I can do.
