I just had my dating ultrasound at 12w and the doctor revealed that Baby is measuring more like 13w! That was very exciting but I just had a few questions about that Is the 13w dating based on the measurements and development of the baby? Or is this indicating that the date of conception was actually earlier than what I first thought?

Based on my calculations, 12 weeks pregnant was accurate since my LMP was actually 12 weeks ago, and I used an ovulation test while TTC, to time intercourse, and I pretty much could pinpoint what day I most likely conceived. Now the 13 week dating throws that all off and we would avis net dating assistant conceived on a day where I was not ovulating.

I know that this really doesn't make a difference in my pregnancy and the baby and I probably won't get acfuracy concrete answer anyhow. But I scqn such a calculated person and shedding some light on how wcan dating ultrasound works would be super! Anyone out there had the same experience? We conceived using IVF so are able to pinpoint the conception date.

Babies grow blind dating 2006 subtitle their own pace. Some weeks they grow faster than others. With my first pregnancy my due date continually got moved up because of the rate he was growing. Thanks so much for your asian parents dont allow dating That's so interesting that craigslist phoenix az dating can have growth spurts some weeks and that reflects the progress of their development.

I figured the dating was based speed dating sydney 18-25 the development of the fetus but it's weird to wrap your head around the fact that you are actually further along in weeks when I have been mentally prepared to enter a different week! Same thing happened to me! 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!

And I thought, huh, how weird, because I was using an OPK and thought I knew exactly when I ovulated! Speed dating melbourne 20s OB decided against changing my due date at this point though. Babies can definitely have growth spurts from now on. Generally a dating scan before 12 weeks is most accurate dating indianapolis the growth up till then is more predictable ideally weeksafter that genetics, etc come in to play and there will be variation.

Our midwives don't change due date any time after 12 weeks as long as there has been a dating scan or reason to be sure of dates-like ovulation kits but if it appears the baby is getting ahead or behind they monitor a little closer just to keep an eye on things. Dating us are fossil dating cancer detection circulation problems more accurate the earlier they are performed. And even an 8wk us can be off by days, which is probably why doctors won't change due dates unless lmp and us are off by a week daging more.

Datijg accuracy goes down with time so a 12wk us being off by 7 days sounds possible. If you know when you ovulated, then I would go with your original due date. I would also not let my doctors move up my edd if I thought my original edd was correct because most doctors won't let you go past 42wks. If the new edd is a week sooner then you bagy be induced unnecessarily. I hope this makes sense. The dating scan is based on baby's crown to rump length.
