I know how you feel, I was a huge worrier during both of my pregnancies. Just waiting for the moment when things would go wrong. It really started when I read the book "What to expect when you're expecting". It should have been called - "All the things that could possibly go wrong during your pregnancy"! My husband had to take it away from me lol. When I would tell my husband all my worries he would say, "it's out of your hands". So I would just try to remind myself of that. Just try to relax, easier said than done I know!
