What symptoms do you look for?

[tummytickler]

Thats it really! What symptoms do you look for during the 2ww? I am ttc dc5, but this is first time I have needed or wanted to do more than shag dh and see what happens!
So, what symptoms of pg am I looking for before af is due?

All the things that mean AF is due are also symptoms that you may be pregnant.
Hugely, hugely frustrating (from someone who was TTC with little success for 7 years on and off).
