Should I worry. Have serial growth scans due to a past stillbirth had my 1st at 28 weeks and all measurments were large (90th or more centile ). Today at 32 weeks The tummy has gone from above the 90th to the 60th mark. Leg has dropped from 60th to 40th and head is the same as 28 week scan. Should I worry ? 20 week scan showed my baby was 50th centile but I don't know if the 20 w Scan means anything in terms of growth? They said to come back in two weeks to 'check ' on the growth. I'm seriously worrying it'll drop again as there 'supposed ' to stay on their centile line
