The most accurate time to date you pregnancy is after 8 weeks through to 13 weeks.
Your booking-in appointment is your first antenatal appointment with the midwife (sometimes at your home, sometimes at hospital).' And it was like, 'Well, what do you mean, why have we come this early?' And she said, 'Well, why have you come this early?' And, as I say, 'Well, because you sent us a, the date through to come, you know.We're meant to be, you know, you're meant to, dating scan between 10 and 12 weeks. And our midwife spoke to someone in the ultrasonography department, and they said that they wanted us, because of our past history, because we had an anencephaly baby, you wanted to scan us at 10 weeks just to, so that it gave you more time to prepare to then do another scan at 16 weeks, which is the original plan'. ' I said, 'All I want you to do is to tell me if my baby is healthy and normal'.A scan can also help you bond with your baby and help you to relax and start enjoying being pregnant.This scan can be carried out from 6 weeks to 18 weeks. This scan will provide you with the following information: 1. Less than 5 weeks: pregnancy is unlikely to be detected by scanning 5 6 weeks: A small gestation sac is seen 6 8 weeks: A small embryo around 5 mm is seen at 6 weeks 9 10 weeks: Limbs begin to develop 11 12 weeks: Baby curls up into fetal position Dating scans may be done after 12 weeks if the nuchal has not been done and it is too early for a morphology scan Your Doctor may request this scan if you are unsure about your dates, you have bleeding or pain or if your doctor suspects a multiple pregnancy.This makes it easier to see the uterus and ovaries as the full bladder pushes away the overlying bowel area.On some occasions it is still difficult to see and so we may ask if a more detailed internal ultrasound scan can be done trans-vaginally.
