2 miscarriages and now pregnant again

Hi everyone,
I'm a young woman, 22 years old, and unfortunately had two miscarriages this year—one in January and one in July.
Now I'm pregnant again, but fear is overshadowing my joy. I'm currently 5 weeks pregnant, and my first ultrasound is scheduled for November 29th, so I have to wait a bit longer. The test lines are thankfully getting darker, but I'm just so scared, and unfortunately, I don't have anyone who understands my fear.
Hopefully, there's someone here who can understand me and support me during this happy yet anxious time.
I hope that in two weeks I'll be able to see a beautiful little baby on the ultrasound with a strong, beating heart!
