I had a baby appointment today, i am currently 35 weeks 5 days pregnant, he did the fundal height & i am measuring only at 31 when last week it was 34, so he scheduled an ultrasound for thrusday , but i am just really nervous, has anyone else had this problem during the last weeks of prwgnancy????? Do you think he might have dropped?
