Hi David,
I personally started worrying before we actually started trying! Because of DH medical history I knew it would be a problem before we even got engaged.
Weird though that I still took the pill until we were sure we would be ready if it just so happened to work straight away. What a waste of money that was lol.
I agree that everyone probably starts to worry at a different stage depending on their own history/expectations/situation. I have a friend who started complaining after trying for 1 month because her first was conceived straight away!! You can imagine my reaction I'm sure!!
I have recently started reading your book and was hoping DH would but he doesnt really read so I will just have to extract info and force feed it to him. Thanks for the articles and please keep them coming!
