Paranoid after miscarriage.

So im 8 weeks & 3 days today! Very happy to have gotten pregnant after my loss two years ago. But Im super paranoid with this one & over analyzing everything. I just want everything to go right this time. On top of it my last dr visit all I got was blood work done mind you I should be having my 8 week ultrasound right? It would make me much more at ease to see my babys heartbeat. I really wanna pass up this first trimester all the time. Its scary!

Is anyone out there going through my paranoia as well?
