Hello I’m 37 +3 days and on my last two scans baby girls head measurements of bpd and hc are measuring low 5 percentile and 5.7 percentile all other measurements are looking ok. My genetic screening didn’t show anything. Looking to see if any of you moms have gone through this and if so did baby just have small head or did they have microcephaly? Thanks
