Trying again

So after numerous losses I've been diagnosed with a blood clotting disorder. This has caused most likely most of the miscarriages. Having got a diagnosis and treatment plan I felt positive and that I could get the baby I dreamed of. Roll on a month from the diagnosis and I received a copy of the report in the post that was sent to my GP. Having read the report I feel like all hope has gone. Apparently I'm at extremely high risk of having a premature baby. I can't help but feel like I could potentially be putting my dreams above the health of ant potential baby that I could have. if you were told that the chances of you being able to carry a baby to term were extremely unlikely would you still go ahead and have a baby? I'm not asking any of you to make a decision for me I just want opinions to help balance my thoughts and try make the right choice.
