Saph, I feel exactly the same...
I't a mix of feelings when people announce pregnancies...
'why not me?' question always popping in my head... and it's true the whole world seems pregnant!...

I was the first one of our group of friends wanting a baby... They were all not sure about starting a family but it was always what I wanted the most!... All my friends now have kids and already trying 2nds... but me

But like Cassius said it come in waves... and we just have to think positive I guess...
