First trimester anxiety/depression?

I am 5 weeks and 5 days pregnant. I have wanted to be a mom my entire life. When we decided to ttc I was diligent about doing everything I could to make sure it happened. It took much longer than expected. Anyway! So finally it has happened and all I can think about is losing the baby. It's taking over my life. I have become moody and irritable and I know it's taking a toll on my poor amazing and supportive husband.      
Our first ultrasound is June 22nd. I just feel like I can't relax until I see our baby. I'm so scared it won't be there. I don't even feel pregnant. Very few symptoms (fatigue, off and on sore boobs, indigestion.)My HcG levels were checked last week and were in the high range but I still can't relax. Has anyone experienced this? I'm driving myself and everyone around me crazy. All insight appreciated. Thank you💞
