I thought I miscarried last week been to the hospital had a vaginal scan and they said they couldn’t see anything

Had another scan still couldn’t see anything but my blood work came back as 425/475 (I can’t remember) I was also told not to come in for more bloods but they want me to go in for another scan on 7th January as they think they can see something.

I’ve decided to document preg tests as I don’t want to get my hopes up

Left is Thursday 1st wee of the day.

Right is today (Saturday) 4th wee of the day

The test is darker ... has anybody else had this happen??

I know I keep asking these questions I’m just so confused & don’t understand why I have to go for a scan instead of having my bloods done
