I want to wish you lots of good luck. I'm so happy that you found a wonderful SO. And it's also great that you have a list of things you want to do and accomplish during this time in your life. Having positive and fulfilling activities REALLY helps with the waiting game. Waiting can be very tough when it comes to TTC. But, since you seem happy and busy, I think it will not be too tough for you.
I'm a frequent visitor to the Preg. boards and am 42 years old. My DH and I have four children and I am waiting for him to give me his blessing to try for just one more. We have a solid marriage, a deep and great love for each other, and our children bring us lots of happiness. Things can be hard sometimes, I won't say it's all roses, but overall our family is doing well. I would like to give my son a brother (he has all sisters) especially since he is asking for one! Hopefully my DH will give the green light sometime in the next year or two!
Again good luck.
I want to wish you well on getting one more. I wish you baby dust on having a baby in your arms in the next few years.
