missingbaby- I am so so sorry for your loss. What a horrendous shock
If you are negative for E I assume your Rh E genes are double 'lower case' e (e e).
Have they tested your DH? If he is double 'capital' E (E E) then any baby will sadly also carry 1 capital E and therefore your body (well, blood actually) could still recognise this as "alien" and start attacking the baby's blood cells- causing anaemia. BUT if your DH is E e then you have only a 50% chance of having the antigen your blood reacts to (E).
Even if a baby does carry the 'E' that your blood reacts to, it does not always react, hence why they start of by monitoring your antibody titre levels and look on scans for fetal hydrops (accumulation of fluid in 2 or more fetal compartments, including the subcutaneous tissue, pleura, pericardium, or in the abdomen, which is also known as ascites) or signs of anaemia. Generally the maternal blood doesn't mix with the baby's blood until the second half of the pregnancy, usually not until the 3rd trimester (unless an accident e.g. severe bump) could cuase mixing earlier- so until that time any baby is pretty safe. That's why they really step up monitoring later in pregnancy.
If I was in your shoes (which in a way I am, but I only have a 1 in 2 chance of carrying a baby with the antigen I react to- as DH is Ee- and neither my DCs have suffered from HDN although they think DS was heading that way, but was born for other reasons at 30 weeks before my blood could start causing real probs for him- and he's now aboslutely fine thankfully) I would go for it again, as their is a chance you will not need intrauterine blood transfusions and even if you do like you said you still have a 90% chance of carrying the baby to term. The stress of it all will be hard but if you're fully prepared for all the testing etc. you'll need I would go for it, or else you might regret never trying again down the line.
Wishing you all the luck in the world xxxx
