five weeks

I went in for my five week beta last Friday and according to my RE, my levels look good. So, I am scheduled for a first ultrasound this upcoming Friday at 6 weeks. It still hasn't sunk in that I am pregnant. Physically I'm not really feeling any symptoms (which at times concerns me) but I think naturally I am just somewhat guarded at this point.  I am a bit nervous already for the ultrasound. I am no where near as freaked out as I was with my last pregnancy at this point, but still a little scared. Fingers crossed for more happy news!
