i am soo sorry for your loss
it does happen a bit- but b/c alot of people do not go for u/s until 12 weeks, often it happens without people knowing.
If you feel you need to speak to other people that have been through the same thing, please feel free to PM me as i am on another forum as well that has a saturary for mums who have lost either one or both their twins.
take care of yourself and even though your bubba did not reach its full potential, s/he lives on in your heart .
take care
odette
