Annoying!

FGM • TTC #2 at 42. Wishing everyone sticky and healthy baby dust!
Why is it that I can see some comments but can't see others?! For example, I'll find an interesting post with information to which I might want the answers and it will say 8 comments but I can only see/read 3. 
Do I have some strange settings or something? This happens on almost EVERY post I click on. Argh!!
