I think also that I'm just at that stage where I'm overly sensitive too - sooooo many friends are pg or have just had babies - and I really (obviously) want to fall pg, but since I'm not even getting AF I can't. So it's really frustrating. I was looking at pics of a friend's newborn on the weekend and they made me cry... luckily I was alone at the time. Also, I'm really having those "what if I can't fall pg" thoughts - because right now, what's stopping me is a lack of ovulation, so what if once we get that sorted (somehow?!) and we spend a few months... or a year... temping and BDing at the appropriate time.. and we still don't fall pg? Then we'll have another hard road to go down. I know I shouldn't stress about that, but you know how the female mind works...
ETA - Lucia - your sister in law does sound rather horrible - I hope you beat her in her 'competition'
