Then after 4 days it goes up to 30.5 cm on 2nd USG and again after 4 days it went up to 36 cm on 3rd USG with no problems in baby. Then after on 4th USG in 32 weeks 3 days of my pregnancy, it reduced to 30.7 cm and then continuously constant with 31cm in 35 weeks 5 days on 5th USG with no abnormality in baby. Plz tell if any need to concern ?
