I'm not sure if this would help you or not, but maybe you could try having a specific goal for during the TWW. Something that would really occupy your thoughts and your time. It could be something to do with a hobby you enjoy, a new hobby you've wanted to start, or just some kind of change in your life you'd like to make. I wish I would've come up with that idea sooner, because it's really helped me out a lot lately! I started doing some experiments, making my own mixes for my face and hair since they've been problem areas lately, and I've also started researching how to cut my own hair since I haven't had a trim in a year! They are really simple things, and nothing major, but it's been a good distraction. Especially if you only need to get through an extra five days or so, I'm sure you could come up with something that might help keep your mind off TTC!
I understand how hard it is to think of anything else, and to fight that urge to poas, but gradually you can pull away and take some of the pressure off yourself. You don't want to get to the point where you're so stressed you get totally burnt out and need a break, right?
Best of luck to you! I don't have facebook, but if I did I would add you.
