Has anyone had 1st u/s with Rainbow?

Torraine
Hello ladies. I had a miscarriage on 5/30/14 and didn't make it anywhere near my first appointment. Only when I started to miscarry, and had the emergency u/s, I was able to see the empty sac. This past Monday I had my OB confirmed appointment and u/s and saw a little bean and heard it's heartbeat. All I could do was cry, I wasn't sure how to feel. I got so attached to the baby that I lost and never got to see them and I know I should be happy but I'm still so scared. I was just wondering if anyone is feeling the same way. I'm sorry for the long post.
