jo - i'm sorry you didn't get the answers you were after, but barbara is right even with an answer you still begin to question. did they do any other blood tests to check for anything else or just the cmv?. i know a few of the ladies here have waited until after 6 weeks to have another lot of bloods taken to check for clotting disorders as these will not show up whilst you are pg or in the 6 weeks after a loss. it might be something to think about.
Have you thought about doing accupuncture or something to help with your sleeping, I was very sceptical about it after my loss but i initially went for stress and found that it helped immensely, in both calming the mind and relaxing the body and also in making me healthy and strong again to think about and even conceive again. Just take all the time you need before trying again, only you will know when and if you will be ready. thinking of you hon, i'm so sorry again for your loss and I'm so sorry you have no answers.
