How to ease my mind off of a MC?

To keep it short, I’m supposed to be 10 weeks tomorrow, but I’m measuring behind.

At my last appointment, I had a abdominal ultrasound and was measuring about 5-6 days behind but baby had a HB of 144. I was supposed to be 7w5d but measuring 6w6d.

I lost my daughter at 6 months pregnant a couple years ago due to a numerous of reasons (basically she stopped growing). My next ultrasound is this Friday.

How do I ease my mind from the thought of a miscarriage?… I can’t help but to continue to read horror stories and google is not friendly

Every day I’m wondering if the baby is okay or not. I wish I could have an US everyday to help with my nerves.
