Remember that stress isn't good for you or baby. I think the most stressful part is trying not to get attached. After I had my m/c, with my next pregnancy I eventually let go of the stress because I decided that even if baby only survives 6, 8 or 10 weeks of gestation that a baby is a baby and it counts and no matter how young baby is it deserves my attachment, even if s/he doesn't make it, s/he is important and deserves my attachment.
