Ok good! He said some people just carry higher than others. The part that worried me was him saying we need to keep an eye on it
No it's not bad, you're supposed to be a cm for every week of your pregnancy, give or take 2 cms in either direction. So you're almost 24 weeks, measuring 26 is still considered "normal". It may be your amniotic fluid, fluid intake, position of baby, etc causing the difference. Unless you're consistently measuring a lot ahead it's not a big deal, it may just mean a big healthy baby!
