First trimester screening..

I have to go get my blood work done today and my ultrasound on the 16th for my first trimester screening. I am so nervous.... not because I'm extremely worried that something is wrong with my baby because no matter what I will carry it to full term and deliver but I'm scared that the baby is already gone... I had a mmc in September. I thought I was 12w and went to the er for minor spotting and then they did an ultrasound and told me my baby had died a few weeks ago. I'm so scared that this is going to happen again. I'm trying so hard not to get my hopes up but also to be positive! I just want to go full term and deliver a happy Healthy baby..
