Nothing showing up

Chelsea • Homeschool mom due with #5 in December, miscarriage between #2 and #3, follower of Jesus Christ
It's showing no posts for me in any of the sections ("Participated", "Created", etc), so I have no way to go back and look at replies, etc. And usually when I get a notification that someone replied after me or such, I also can't see it. (When I click on it, it just takes me to the community page and not that specific post) Is there something I need to do to fix this?
