Mine was touching the cervix at 20 week scan - had my 32 week scan last week and it's not 4.5cm away from the cervix They do move, my midwife told me that if it was >2cm and less than 3 then there could be more bleeding during birth and the bub would need monitoring - so I'm really happy it's moved from touching the cervix to 4.5cm

Good luck - I'm sure you'll be fine, and it's good that you're prepared in case it doesn't move as far as "they" would like
