Hi, My wife is 34 weeks pregnant with our first child and I wanted to ask a question regarding if I should be concerned by what looks like accelerated Head Circumference growth based upon scan data.
My wife had an ultrasound scan on 25/06/20 (32 weeks) and the HC measurement was 300.7mm (66th%) - our scan yesterday (09/07/20 - two weeks later - 34 weeks) is now measuring at 334mm (>95th%) which seems like a big jump in 2 weeks. My wife queried this with the sonographer and a rather junior midwife and they have said everything is fine as the Estimated Fetal Weight is still in range (although that has jumped from 63rd% to 85th%) over the 2 weeks. At the bottom of the scan reports the impression states "Growth within normal limits, normal AFI and Umbilical Artery Dopplers. EFW plots within upper normal range on GAP GROW chart."
My wife has had 2 diabetes tests during this process - both have been cleared as having no signs of gestational diabetes (both tests were as a result of my wife asking rather than being requested). We are just concerned about the HC jump and wanted to know if there is anything that we should be asking or if anyone has been in a similar situation - your feedback would be greatly received. Thanks
