Does anyone else have (or had/will have) a pregnancy journal? Whether it be a homemade one or a store-bought one.
I bought one shortly before we started TTC and I was so happy to have it after we got our BFP! I really love being able to keep track of all the little details of my pregnancy. I already love going back through it to see what was going on earlier in my pregnancy, and I figure it'll be great when we TTC/pregnant with baby #2 to be able to compare what I'm experiencing. I'm sure my LO will also look looking at it, or at least I hope.

My journal doesn't allow a lot of space for just writing, but I figure I do that here enough and DH and I have a pregnancy blog, so we're covered. My journal has a calendar, sections to keep track of my weight, belly size, doctors visits, ultrasound info/pics, a to-do list to prepare for baby, etc. etc. etc.
In case you're interested, I got 40+ Weeks: The Essential Pregnancy Organizer from Amazon.com. I love it.
I've also heard great things about the What to Expect When You're Expecting Pregnancy Journal.
