Trouble conceiving?

How do I deal with the disappointment of not conceiving? My husband and I are trying for our third child. Our first took two months to conceive, our second took 3 or 4 months. We have been trying for about 10 months for our third and nothing is happening.

I am extra disappointed this month because I really thought this was it as I was having symptoms that I didn't have in the previous unsuccessful months. Alas, my period arrived last night and I was more than surprised.

I am overjoyed that we have two healthy children. I love them with every beat of my heart and remind myself how blessed I am to have them. But I really would LOVE more children, so the difficulty I face in not being pregnant each month can be really hard to bear sometimes. I find it hard as well when people flat out ask if we are trying again, as most people know that I always wanted a big family. I just say,"Yeah, we have been trying for a while", but I feel like saying,"Yeah, it's taking ages and I'm devastated each month when I get my period".

I saw a specialist recently who told me to wait a few more months before they actually do any specific tests, he reckons that it'll be OK given we already have two kids and my periods are regular and I am only 31.

I just really want to know how to deal with this disappointment. At first it was OK, but now as each month passes, I get more and more dismayed. Please be kind in your responses as my heart is already aching. Thanks guys.
