Favorite pregnancy journal

willst

Last pregnancy i was given a pregnancy journal that used "lunar days" and it was just to confusing. I didn't use it that much and now that i'm going back to compare things that are happening i'm really bummed. This pregnancy i'm going to try to be much better. What journals/books did or are you using? Do you love them? Some of my IRL friends used the belly book and thats what i'm thinking but wanted to talk to you ladies first. TIA
