Fetal growth restriction (Intrauterine growth restriction)
Every pregnant woman wants to know her due date. But a due date calculated from last menstrual period with a due date calculator often doesn’t match the due date that is estimated by ultrasound also known as a sonogram. During an ultrasound, a technician spreads a warm gel over the lower part of the abdomen, and then presses a tool called a transducer against the belly to examine the fetus using sound waves.

In early pregnancy, especially before 11 weeks, it is usual to have a trans-vaginal internal scan , where a probe is placed in the vagina. This gives the clearest and most accurate picture in early pregnancy. The person doing the scan spreads a special gel on your lower abdomen below your belly button and above the line of pubic hair. He or she then moves the scanner over the gel, sometimes pressing down, until the uterus womb and pregnancy can be seen.
That may give some information about your pregnancy, but it is less clear than an internal scan and that could possibly delay diagnosis. There is no evidence that having a vaginal or an abdominal scan will cause a miscarriage or harm your baby. If you bleed after a vaginal scan, it will most likely be because there was already blood pooled higher in the vagina and the probe dislodged it. All too often, a scan at 6 weeks shows very little or nothing, even in a perfectly developing pregnancy, whereas waiting a week or 10 days will make the findings much clearer.
Most pregnant women are referred for their first routine or booking ultrasound scan somewhere between 11 and 14 weeks of pregnancy.

For some people the week, mid-pregnancy scan or anomaly scan is the point at which they discover their baby may have a health condition. Many had not fully realised what the scan was for and were not expecting to hear this news. They were looking forward to seeing their baby and expecting reassurance. Looking back, many people stressed that, although they did not want to frighten other parents unnecessarily, they would recommend having someone with you for support.
She did not really appreciate that the week scan looks for particular conditions, despite And that was, that was all I thought was going to happen, because there couldn’t have been anything wrong because everything so far had told me that everything was okay. And even though I read the leaflet that said, you know, this condition and that condition and – none of it really sunk in and it wasn’t, everybody had suggested to me that the scan was to make sure that everything was right, not to tell me what was wrong.
And, you know, I can look back and think, how stupid I was that I didn’t actually stop and think, why is the NHS investing this money in me if everything’s going to be alright?

How to Calculate Your Due Date
A dating scan is an ultrasound scan to determine how many weeks pregnant you are and your due date. Read on for more information about what a dating scan offers. A dating scan might be recommended before 12 weeks to confirm your due date if you are unsure of your last menstrual period or your date of conception. The scan is optional and not everyone will have it. You can discuss whether you want or need a dating scan with your doctor or midwife.
This is also how your doctor will estimate your due date by counting 40 weeks For example, your anomaly scan (TIFFA or ultrasound level II scan) may date.
Throughout my pregnancy , I’ve received two different due dates — one came from my very first ultrasound, when my baby was barely the size of a blueberry, the date that was then subsequently stamped on my record as “the” due date. But then there was a second date, the one that showed up on my next couple of ultrasound scans. This date was a few days earlier. It’s also the date that I prefer, not only because I’m now 38 weeks pregnant and ready to get this baby out, but because it matched the date I’d calculated on my own using information I looked up.
And how much does it really matter? After all, as many moms know, due dates are just educated guesses. Traditionally, estimated due dates are calculated by taking the start date of a woman’s last menstrual period and adding a year, subtracting three months and adding seven days, a method known as Naegele’s rule. But that method doesn’t account for irregularities in a woman’s menstrual cycle — if she has a longer or shorter cycle than 28 days or any variability with ovulation, for example.
That’s why the American College of Obstetricians and Gynecologists recommends doctors use ultrasound measurement in the first trimester to establish an estimated due date. The most accurate way to date a pregnancy is with an ultrasound done between 6 weeks and 8 weeks, 6 days, according to Dr. As a woman’s pregnancy progresses, fetuses develop at different rates, which is why an estimated due date from an ultrasound measurement during the second trimester is less accurate.
