Hi all! 
Pregnant with my first, will be exactly 9 weeks tomorrow and will have our first appointment. Ahhh so anxious and excited and nervous! I have no idea how i will sleep tonight lol. 
Anyone else have thier first sono at 9 weeks? What should i expect? Seeing/hearing heartbeat? Movement? 
Thanks :)
