Has anyone measured small for dates? I'm measuring 4w behind by fundal height (got measured twice this week) and they have noted insufficient maternal weight gain. They weighed me today and I've put on 2.6 kgs from conception and nothing in the last 4 weeks... I thought it was more than that, but nope. Any ideas? Baby is currently breech but that isn't really a concern at 23 weeks and probably explains the fundal height but not the lack of weight gain. Going for an ultrasound in a few weeks for an EFW.
