Can dating ultrasound be wrong
Most dating scans are done with a trans-abdominal transducer and a fullish bladder.
If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures.
My baby and belly have been measuring 3 weeks ahead nearly my entire pregnancy.
Part of the reason my due date is off is my own fault, as I wasn’t sure exactly when my lmp was.
This is presuming that the pregnancy is actually at this stage of development.Because babies are born premature too, so being ready early is best. Sometimes they are late, but the Dr will watch you closely. Hi...i went to ultrasound yesterday, the doc said i am 16 weeks and 5 days & i was like what! and if you're that worried prepare ahead..if you have to get a planned C-section if baby is coming your water still breaks you'll still lose mucus plug and you'll still have a show..you're C-section date is wrong trust me that baby will let you know it's time..enjoy your pregnancies and be happy that you're bringing a beautiful new life into the world stop stressing over everything..luck to all They dont change your due date but i know for a fact that the scans can be wrong sometimes as i have had 2 of my kids come out on the date that I had predicted and the scans were about 14 days off.For transvaginal ultrasound you can have an empty bladder Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.
For example if you a tiny sac can be seen in the uterus, but the baby and its heart beat may not be detected yet.
Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 - 5 days of accuracy.
