Constantly worried

SG

This is my second pregnancy, i had a mmc in August last year. I am 8w4d pregnant today. I had a scan at 7w3d and everything turned out to be great. I am still constantly worried if something is wrong. My next scan is on 9w2d mark. I had a weird dream that i am losing the pregnancy, it is probably because i am constantly thinking something is wrong. For those having a rainbow baby, how did you ease your worries?
