It looks flatter than my boys. I've not seen one of mine look like this before. I'm not sure where all their scans are at moment though. I must have put them somewhere when we moved. I'm still quite surprised it's not an obvious boy but I'm trying not to get my hopes up too much.
My midwife tried to find babies HB last week (11 weeks). She found it for about 2 seconds and then couldn't find it again lol. I've never had my own :)
