Pregnancy Book, Baby book, TTC Book?

You know how some women have pregnancy books during pregnancy and then a baby book, I've been thinking of putting something together to show my future children exactly what mommy and daddy went through to conceive them, like a TTC book. Here are a few things I'm collecting while we TTC:

1. All dates. (doctor's appointments, ultrasounds, blood tests)
2. Appointment Cards. (to all the different doctor's I'm having to visit... gynecologist, endocrinologist etc.)
3. Monthly Journal entries (obviously something more eloquent than my BnB entries I'm gonna buy some pretty paper and write an entry for each month we get a and what I'm feeling, the high's and low's of TTC)
4. And eventually everything that happens the month we get our (symptoms, HPT, blood work, EVERYTHING)

Anything else I can add to my collection?
