Early Pregnancy Anxiety

Is it just me or is anyone else just a basket case when they’re pregnant? I found out almost a week ago I’m pregnant with baby #2 and I have moments where I am on cloud nine and others where I’m totally freaking out and terrified. I definitely have some ptsd after having 2 miscarriages back to back. Then I went on to have my now beautiful and healthy 14 mo son. I just want to feel like I’m not losing my mind and that this is normal. This anxiety is killing me!
