Small gestational sac, strong heartbeat

Hey everyone. I’ve been having ultrasounds weekly due to a small gestational sac which measures almost 2 weeks behind baby.

I’ve read online the sac should be a minimum of 5mm larger than the embryo. Mine right now is only .1mm larger. I am fully aware a miscarriage is likely. I just wanted to find others who have been through this.

I’m almost 10 weeks. Here are my previous 3 ultrasounds during week 7, 8 and 9. As you can see, the baby just looks so squished in the 9w2d ultrasound. :( praying but fully anticipating the worst. Any support or stories appreciated.
