Terrified...

Today is the day! I go in for my first Dr apt and u/s today! Last time I went in at 5w and got the bad news. Today I'm 7w+1 or possible mid 6w as I think I ovulated late. I'm nervous as hell!!! I'm so afraid to hear bad news again. I woke up at 3am wide awake and haven't slept since. The make it worse my nausea has calmed a lot today which is scaring me more. Luke is leaving work early to be there. 3 more hours!
