Pregnant after miscarriage

Hey ladies! So I just recently found out I was pregnant again. Last year when I got pregnant was my first pregnancy. We tried for almost a year until we decided to give up for now, less than 2 months later we found out we were expecting again! The hubby and I was so happy. But here lately I've been so paranoid. I'm so terrified it could happen again. I have anxiety and my anxiety has been through the roof about this. I'm doing the best I can not to stress myself out over it. I'm trying to be positive. My doctor is suppose to call tomorrow morning to set up my first appointment but I keep wanting to go to the hospital just to make sure everything is okay and I know I should just wait but I feel like I'm just being paranoid. Any of you ladies been through this? How do you deal with it? Thanks in advance!
