Hello everyone i'm new to this so bare with me And she was born on the 14th like I said! Just thought I would take 5 mins to reply to this post. I concieved non-id twins a couple of years ago. A couple of weeks later it was still different eg. None of these sizes corresponded to my dates as I know EXACTLY when they were concieved as we only had sex day 11 that one day during my fertile cycle.
A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. 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. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.
Back to Your pregnancy care. Ultrasound scans use sound waves to build a picture of the baby in the womb. The scans are painless, have no known side effects on mothers or babies, and can be carried out at any stage of pregnancy.
