How to not worry!

Hey guys! I am currently 5 weeks and 6 days pregnant so almost 6 weeks. This is my first pregnancy and I am so excited! I've wanted this baby for awhile so it scares me to death that I might miscarry. How do I not think about it and just stay excited for our little one? I probably should quit reading posts on here especially cuz a lot talk about how they miscarried and it makes me worry. I got pregnant our first time trying too and I am due on my grandma's bday. She passed away last year so I believe this baby was meant to be. But how do I just push miscarriage out of my mind and just focus on the good?? Any ideas?? I think the fun new emotions are playing a role in this :)
