First scanned for rainbow baby

I have my first scan today at 6w5d after having a missed miscarriage two years ago. We waited a long time to start trying again because I honestly wasn't sure I could handle another miscarriage if it happened. It sent me into a pretty deep depression. I remember being so excited to see my baby and finding out there wasn't a heartbeat was one of the worst moments of my life. I am so, so scared. If you've got some to spare, positive vibes/thoughts/prayers welcome. Praying for healthy, sticky babies for us all!
