How do I not worry?

So this is my first pregnancy and I'm 9 weeks. I had my first ultrasound a week ago and everything was great. But for some reason every single day I'm so worried that I'm going to miscarry and I know it's not good to worry. Every time I cramp or feel funny i get so scared. I just wish I could see my baby every day just to make sure he/she is ok. So just looking to see what's some thing I can do to not worry or to comfort myself?
