Had a growth-scan at 29weeks, baby was measuring big, in top centile, no problems. Had another growth-scan today at 35weeks, he's dropped a centile! Doctor said I'll need another scan in 2weeks in case growth slowing down too much, in which case may need to be induced early.
Has this happened to anyone else?
Really worried! 
I have HG, could this be caused by not eating enough/keeping enough down?
