Hi.. I know it isn’t a great photo but I am worried because I can see a part of the head missing..what do you think?

Also.. when I went for a scan I was 8+5.

At first the baby measured 5+3 but at the end they confirmed 5+4. I asked why is less that what actually is and they said it depends from many reasons, position , person that measures ( at first there was a trainee doing the scan and then a doctor came to check).

I am so worried as I had a miscarriage and the baby wasn’t growing and at 12 weeks they saw that the head had a black spot(probably a hole)... I am so worried and sad
