but it did not happen on my first try. I began my donor egg journey in 2004, and after numerous failed cycles I am the proud mom of a 4 1/2 year old son! It was a long road, I started the same way as you did, being so careful about everything, and it's important. At the stage you're at though, I think drinking alcohol and coffee in moderation is fine (while you are cycling) but you need to do what you feel will bring you success. Sometimes we need a stress reliever if it won't hurt our chances of pregnancy Whenever I cycled, I made sure to color my hair the week or two PRIOR to transfer, so it would last me until after the (hopeful!) first trimester.
There is a related board http://www.network54.com/Forum/247611/ where many "yellow board" poster go after they achieve success, but you are welcome to post here or over there anytime. Lots of luck to you!
