Just realised I posted this under pregnancy but it may not be much use there!:
I am 40 and did worry about being able to conceive again after I took nearly 2 years to conceive our only daughter. However, I have conceived TWICE IN THREE MONTHS (lost a baby in Nov 09) and the only thing I've done differently is listening to Zita West's CD. Honestly.
I swear I don't get paid commission for saying this. In fact I wrote to the Zita West clinic with my happy news 3 months ago and was a bit dissappointed when they didn't even acknowledge my email. But who cares?? I'm pregnant again and that is amazing.
Love and luck to everyone!
