I'm going crazy!!

I've read many posts with women who've gotten ultrasounds at 6 or 7 weeks. My ultrasound is scheduled 2/28 which would make me 9 weeks. I wish my doctor wasn't making me wait so long for this viability ultrasound! Any advice on how to keep myself from going crazy?? I'm worried something might be wrong as it's my first pregnancy...

I have no morning sickness, just occasional nausea, cramping, back aches, acne, night sweats, some boob soreness and ravenous hunger.
