Advice for the first few weeks

This is baby #1! We are over the moon excited! We don’t want to tell family until at least the first appt. Since I’m not seeing the doctor until then and have no family to ask yet, what advice can you share? I am already nauseous at times, can’t sleep well, and am super tired. I know I can workout and run but it still makes me so nervous to jump around. I will take any advice or tips!
