Baby’s in position

Mummas I need some advice I’m a first time mum and he’s due in 11 weeks and 1 day😩😩 I saw my midwife yesterday for a routine checkup and she said his head is in position already and he’s measuring 27 weeks instead of 28? Are both of those normal? I have a scan on 4d scan on Monday so I’m hoping he’s measuring correctly
