with the girls i felt everything as well - what made it even harder for me to enjoy my pg as much as i would (trust me i still enjoyed it) was that there is no real safe period for twins according to my ob and once you hit 34w you can breath a little easier - but until then there is still a risk that the unforseen might happen (esp with ID twins)

you're right - nature does have it's own ideas - i will be thinking of you and hope everything turns out the way you want it to.
