I know that lots of people love coming here to read the TTC Journals!
I have the Idea that when You do get your BFP and you move on you could put PREGNANT beside the title of your TTC Journal
Also in the last post of your Journal you could put a link to your pregnancy Journal if you move on to have one!
Here is an example
ORIGINAL TITLE ---> Melanie's TTC#1 Journal
BFP TITLE ----------> Melanie's TTC#1 Journal
