I'm just a bit confused.i had an ultrasound on Saturday to check for irregular heart beat which was picked up on thurs (all turned out to b fine heart beat wise),however I got a call from the midwife saying that they are concerned with the size of the baby. It measured to b 3kg on the ultrasound.i am 35 weeks and am just not sure if that sounds that big. Could midwives be overreacting or is it a cover their bum thing to send me for this diabetes test so late in pregnancy?
