Following other app users and bookmarking

Tiffany • 35 yrs old. Pregnant with Baby #2. Due May 26, 2020
I have selected to follow other app users with edd's close to mine but I don't ever see these users posts more than others, etc... How does "following" work?
Also, I've bookmarked pages but can't seem to figure out where I can go to revisit those posts?!
Anyone know how this works?
