Pregnancy nervous

I’m almost 7 weeks pregnant and every morning I wake up I’m so excited and anxious about my pregnancy because it’s the first time ever I’m pregnant, next week I’m having my first ultrasound, and I’m still in the stage where only a few people know about my pregnancy. I feel like it’s driving me crazy that my side of my family doesn’t know I’m pregnant and it also scares me that I’m still at the stage we’re it’s best not to say anything because im early in my pregnancy. How can I be calm these weeks coming up?
