terrified of all the mc stories

I'm about 6 weeks now and I've been through 2 chemicals before, both ended before week 5. I have my first dr visit tomorrow but I really cannot stop worrying. I scroll through the posts of glow and all I seem to read is stories of misscarriages. How can I ever relax??? It is so terrifying that I think I should remove glow and not open internet ever again. It seems like the chances of getting through with a pregnancy are so impossible....help!!!!
