Baby #1 & freaking out

I just found out I'm pregnant last night with a pink dye, and confirmed it this afternoon with a digital and they were both positives. I have never felt so many emotions in my whole life. according to my Ovia app, I am 3 weeks and 4 days. I want to be super excited but I'm terrified of having a miscarriage. This was our first month TTC and I keep thinking there is NO way we will be so lucky and have this baby in September😔 Is there anyone that has been blessed and haven't had to go through a miscarriage?
