They say after 24 weeks, genetics and environmental factors start to come into play, each baby will grow differently now, and that's why ultrasounds are no longer a reliable measurement to determine how far along the baby is. So it's still safe to say you are 27 weeks, your baby is just growing.

When I was 20 weeks her arms and legs were messuring at 22 weeks so they did bump up my due date from june 6th to june 1st... not too much of a bump but still a couple days earlier :)

@bellahali,

What?! That's right! I haven't found anyone else on this app from here lol

Could be a growth spurt
