today is the day ....,

I have my follow up ultrasound in several hours to hopefully see growth and a heartbeat. I am nervous and scared. Please keep me in your thoughts and prayers. Thanks 
Background:
I'm the one who went last Tuesday for an ultrasound and they suspected then that I was having a failed pregnancy due to thinking I was over 8 weeks by a few days and no heartbeat seen or heard and baby measuring 6 weeks and a few days. We personally aren't worried about measurements last week due to that's when we suspect I got pregnant from intercourse activity. So we think just was too early I'm now 7 weeks and a few days by our dates. I'm still not showing any miscarriage signs but throwing up constantly and nauseous.
