Getting nervous

Amber • Hello! I'm 22 years old and married. First time mom❤️❤️
So I'm nine weeks and I'm starting to get a little nervous. I had a miscarriage back in July of this year, but I wasn't this far along. I'm just not feeling pregnant as much. I mean this pregnancy is way different than the first one, but still it's like it's starting to go away. I had my first ultra sound at 6wks and saw the heart beat. It was really good and strong, was even able to hear it a little. But I don't go to the doctor again till the 30th and I'm just getting a little anxious about it I guess. Someone just tell me it's in my head and everything is fine.
