Need some reassurance

Hey everyone basically I’m about 8 weeks pregnant with my 3rd but 4th pregnancy as I had a missed miscarriage last year , but my anxiety stupid thoughts are getting the better of me

like should my stomach be hard already constantly looking in the mirror thinking it’s not growing

Like I should be exciting I’m pregnant but I just feel really down and depressed but I’m so worried I have my first booking app on Monday with the midwife but my first scan isn’t till the 17th may and don’t think I can hold out that long

Anyone else the same
