nervous/ excited

Soooo December 13,2013 I miscarried at 6 weeks 3 days. Its now 2017, I'm 7 weeks and 4 days. I'm nervous but at the same time excited.  Next Friday I go in for my first ultrasound and I don't know how to feel. I didn't make it this far last time. Please send positive vibes and prayers my way I'm super excited to be a mama.
