Bad anxiety with anatomy scan coming up... need reassurance

My anatomy scan is on Monday and I will most likely not have results until the following Wednesday when I see the DR.

My anxiety has been so bad today. I have convinced myself that something will be wrong with her. Ive been looking at past ultrasounds and convinced myself I have placenta issues. I know its nuts but my mind if going crazy. I’ve been crying all day...

I’ve had 2 first trimester losses prior, so this is as far as I’ve gotten.

Please talk me down the ledge because I can’t deal with this extreme anxiety. :(
