My DD went for her 25 week appointment to meet her midwife who asked how everything was going and then wanted to measure baby ,turns out baby is only just on the growth chart so measuring very small . Midwife said dd has a hormone deficiency and will see a consultant at 28 weeks also the midwife and have another scan and will need more scans throughout the pregnancy and may also have to give birth early at maybe 36 weeks ,this baby sure knows how to keep us on our toes
