I can't stop worrying..

So a little background, I'm 6 weeks pregnant and I'm a compulsive worrier. Those two things are not good together. I have had a 5 week scan as I had some cramping they couldn't get a heart beat as it was too early I go back on Friday to confirm everything is ok and progressing as it should. I find myself googling miscarriage rates every single day sometime for hours at a time, I read scientific journals absolutely anything for statistics and reassurance. Has anyone got any piece of advice for me to stop worrying. I originally thought the worry would go at a certain amount of weeks but I think it will just get worse... help!
