UPDATE:

Went for scan and baby us measuring bang on average, must just have a smaller bump. Feeling relieved though definite peace of mind

35 weeks tomorrow, been measuring a teensy bit under since the beginning if my pregnancy, at my last appointment it dropped slightly lower and today's appointment even lower now at 31 (it's been plotted on graph as 32 but midwife definitely said 31 and I saw the tape measure at 31 so must be a mistake). I've been referred for a growth scan but getting myself worked up about this. What was other people's experiences when they were measuring under? What was baby's weight when born?
