How does this app work?

A.

I paid for premium. I am trying to get pregnant post myomectomy and am older. How do you log the start and end of your period? Also, since they changed the logging process and added that vertical chart I log, save, and then go back in and what I've logged isn't there. Finally, did they move the notes feature? Sorry to make the post a b*tch fest, I'm just looking for some help. TY
