I had my dating scan last Thursday and I'm so anxious about getting the results back for the NT/blood test chromosome checks. It's all I can think about. After having two miscarriages very early on in the past, I just hope that this pregnancy is completely successful. What can I do to keep my mind from thinking about it? I recently bought some maternity clothes because my jeans are so tight and I'm worried I'm going to jinx this pregnancy by doing that. I know it sounds silly, but I can't bear the thought of anything going wrong.
