Feeling bad, sad and down.

I'm pleased for them all and of course I was happy to do them each a little momento That they can frame and cherish forever so, me being me, I sat down with each of them, went through some designs and made a start. I've now completed 2 and am part way through the 3rd only I've reached a wall.

You see my fiancé and I have been ttc2 for the last 2yrs, I've kept my weight down, taken prenatal vitamins, had sex as often as we can during my ovulation period and it's just not happened. Every month it get to the week before my period and I get secretly excited, maybe this time, maybe me. And each month my period turns up, as it has today and I just don't know what to do now. People say "stop trying then it will happen" but how do you turn of your biological yearning for another child? It seemed so easy falling with my first, we discussed children, I stopped smoking and BAM a positive pregnancy test, but this time......? Am I being greedy wanting a 2nd child?
