13 weeks, I’m worried about a miscarriage

Pickle

I was extremely tired and nauseous from like 7-11 weeks and now most symptoms are going. This is the exact timing and how things went before my last miscarriage. I’m so worried. I get another ultrasound in three weeks 😩 this one was when I was 11 weeks. How do I deal with this stress? Also do the baby look okay?
