Ohk good (: thats what worried me that he/she wouldnt grow to be as big as he/she should be.
Dont get down on yourself. From my experience i was measuring 4 cm behind with the fundal measurements so dr said about 3-4 weeks small at 23 weeks. At 32 weeks my baby hit a growth spurt and was finally measuring exactly 32 weeks. You have a long way to go. Your baby will keep growing :)
maybe once you have your 20 week scan things will be different although they say the most accurate is the first scan you have done when you're just 8 to 10 weeks pregnant I'm sure it's a little frustrating
I was 14 weeks when i was in the hospital and baby was 12 weeks. Now im 15 weeks so im guessing baby is around 12 and a half to 13 weeks now
