I completely believe (and subscribe to) the idea that one should listen to her gut. Yours is apparently saying "don't put a baby in me!" LOL! Sorry, the sarcasm hit me and I had to share it!
But seriously, almost daily I come up against a decision and feel like I *should* choose "A" but there's something whispering "B, B, B" and I never regret following the whispers. A phrase I've learned is the past is to "not should on yourself." I think any time you choose the path you feel you *should* it's not the right one for YOUR happiness. It may make everyone else happy (Lyndon wants another one now), and it may even make total sense (you want another baby at some point, so just do it now), but that does not make it the right choice for YOU. It's not a matter of being selfish and disregarding Lyndon's feelings, it simply that your feelings are different and personal to you and just a valid.
If you've been trying to, essentially, psyche yourself up for wanting a baby right now, and it doesn't sound as though it's really catching on, then I'm hearing your heart saying it's just not the right time for you.
It sounds like you're trying to make yourself feel the way Lyndon wants you to feel, but it just ain't happenin'. Rarely does good come from making a choice that goes against your authentic self. Heed the signs (like your dream).
I apologize. i'm totally drugged and not terribley coherent. I check back tomorrow
