Need advice

So I just found out I'm pregnant. Which is amazing yet I find myself worried and emotional over things like mc and chemical pregnancy. I don't want any negative energy but I find myself worrying about these things. This is my first child and I just want everything to be okay. I think I've read too much and know a few people that have gone through things like that. I'm a worrywart and a bit paranoid. Any advice on how to keep my mind at ease and to just relax?
