Dating Scan Of At 5 Weeks Accuracy

Can a baby's due date be a month off when determined by an ultrasound?

how accurate is a dating scan?

I was 12 weeks 5 days when I did NT scan and they told me I was actually 5 days ahead of that, so 13 weeks 3 days! Generally a dating scan before 12 weeks is most accurate because the growth up till then is more predictable (ideally weeks), after that genetics, etc come in to play and there will be. My midwife said any scans after 12 weeks aren't accurate as by then the genetic differences will have started to show (eg I'm 5 ft 9 and DH is 6 ft 3 so our baby is likely to be bigger than someone who is 5 ft 2 with a partner of 5 ft 9 IYKWIM). With my current pregnancy I knew my LMP date but didn't get a. I think around 12 weeks is more accurate as early scans can be behind and you catch up by time dating scan comes around. hi everyone i have had the same expierence with my early scan. i went for a scan at 7weeks 1 day and was put back to 5 weeks (15 days) i had to go back 10 days later which.

First Ultrasound! (5 weeks 4 days)

From reading quite a few posts, most people seem to move a couple of days not nearly 3 weeks. Have you gone back through your dates and double checked? I'm sure you have but that is all I keep doing. I hope someone can give you a more comprehensive answer but wanted to add my voice to your enquiry.

LRRSJul 28, Are you going to get a second opinion? My mum and step dad conceived my brother accidentally on their first night together and they've been happy together for 17 years.

I hope it works out for you! Am I right in thinking I just move the old due date forward 4 days?! Sorry if that sounds thick!!

Accuracy Of Dating Scan At 5 Weeks

The first date was based on LMP long cycle! The offical answer is that they are accurate to 4 days. On the other handI know many people who know when they conceived for various reasons. At the end of the day the measurements are just averages. Babies end up all sorts of sizes so it is likely that they will grow at different rates. I know that I conceived on one of 2 occasions in one week. I haven't worked out if those fit with my dates, maybe I will do that!

I know my friend was measuring a couple of weeks ahead at 12 weeks, but is back to what she should be now, at 20 weeks. As others have said, there can be Accuracy Of Dating Scan At 5 Weeks variation! BsmirchedJul 29, Hi new to writing on here but have been reading lots of useful advice from you all.

Dating scans work on the assumption that the length of all babies in the first 14ish weeks progress at exactly the same rate. Which seems a bit odd to me considering that length of cycle, birthweight and everything about the mother vary such a lot. A friend of visit web page had her dates pushed back by Accuracy Of Dating Scan At 5 Weeks 3 weeks, only to have her baby 5 weeks 'early' but with no more complications than you would expect for a 2 week early baby, she is firmly convinced she was right all along!

Sorry to hear it can put some people in such difficult situations. Guess it varies place to place, or my midwife doesn't trust the sonographer! She'd already written Dec 6 on my file the scan results say Dec 2 but they have left Dec 6 as the date for my MAT B1 form, lets face it, won't make any difference to when the little person decides to arrive!

When I had my son, I was moved forwards by almost two weeks and despite what I said they refused to change it. When he was delivered by section at 37 weeks, he was apparently a typical 35 week old baby - small and very hairy! WelshlizzieJul 29, I have questioned this also.

That's so interesting that babies can have growth spurts some weeks and that reflects the progress of their development. The yolk sac lies within the gestation sac and looks like a little round circle inside the pregnancy sac. Yes, my password is:

I know exactly when i conceived can't be any other time unless i'm a medical marvel! I went into meltdown as this has implications for me also but my hubby assures me it just can't be when they said it is!

I don't think it is exact.

First Trimester / Dating Ultrasound

LRRSJul 30, I should have said a super sperm has made my baby - and me a biologist tut tut! Anyway I found this online From early on in pregnancy, babies grow at different rates, so these numbers are merely averages. Your baby's actual length and weight may vary substantially.

Don't worry too much if an ultrasound indicates that your baby is much smaller or larger. Your practitioner will let you know if it's time to worry about how big your baby is.

The size and appearance of this sac will be assessed. I already have twins HTH ps Congratulations! Alternative therapies and fertility Can alternative therapies help you to conceive?

By full-term, your baby may end up weighing less than 5 pounds or more than 9. Hope this doesn't offend you LRRS, and believe me my husband can be a bit of a know, but seriously this guy is an idiot! Personally from my 3 pregnancies I reckon you as women need to go with what you believe - we're usually going to know best about our bodies.

They usually get stuff wrong from the scans. My last bump was huge and from the extra growth scans I had they were predicting a 10 pound plus baby, right up until minutes before he was born by section.

He was 8 pounds 10! Sorry to hear about your situ LRRS. When I said I think Accuracy Of Dating Scan At 5 Weeks conceived later than when you are suggesting she said not to worry as these things even out in the end. However this is absolutely no help in convincing my ex who believes with all his heart this is an exact science. LRRSJul 31, My scan agreed with my dates but when the midwife works it out on some circular thing the weeks vary so that she has put on my notes that i'm a week less than the hospital scan thought!!

LRRS - aren't you very tempted to just say once more that it is his and then just smile sweetly - when the baby is born you can always get a DNA test for proof and to make him feel like a total a e!! You must log in or sign up to reply here. Share This Page Tweet.
