I had my midwife check up for whooping cough vaccine and she did the fundal height check and i was measuring 23 and im 25 weeks putting me in a 5th perctile for my weight height etc. I had growth scan booked in for 2 weeks but midwife has brought it forward and im now having it tomorrow. Im really concerned and worried. They said she was measuring normal at the 20 week scan?anyone else?
