Measuring small?

Anyone else measuring small and things going ok? At my last ultrasound my baby was 6 days behind and was in the 5% range. They had me get steriod shots because they are worried he may come early. Today at my appt my belly is measuring a week and a half behind (which I know isn't too accurate). I have a Level 2 ultrasound in 2 weeks to recheck his growth. Hoping he hits a growth spurt.
