vikki - 107 days ago Rating: 0 (0 votes) The varience of 4 or so days isn't too bad. In the end they will be looking for how much development has happened rather than size. Remember, everyone grows at different speeds and that can give a quircky reading. The person doing the scan should be putting your LMP date in first and then they look at development in line with that. It sounds like the first one wasn't the most accurate one of all of them. It is hard to get an accurate reading sooooo early. I would trust the latter ones and as the baby is continuing to grow, that's great!

MelissaJoanne - 107 days ago Rating: 0 (0 votes) Babies measure differently. The u/s calculations won't be as accurate as if you know your own cycle, such as first date of last period and conception date.

Carmione - 109 days ago Rating: 0 (0 votes) Because babies early in pregnancy can measure differently, that's why u/s techs give themselves 7-10 window for accuracy. It's just a standard- unfortunately that doesn't help us when we're trying to figure out when/where the baby dance worked for us. Good luck to you on figuring out what date to go with...the closer you get to 20 weeks, that's when babies normally all start falling within a certain growth range- between weeks 18 and 20 when they do your frist trimester anatomy scan.

katznkt - 109 days ago Rating: 0 (0 votes) Mine were all different as well. My ultrasound due date varried by more than 10 days, and I had 4 of them. In the end i went with what my doctor said, and well see how accurate he was in another month and a half! If you dont know the exact date you conceived, then youll probably never know for sure, so either go with the day your doctor said, or pick a medium from the ultrasound test.

mommytobe29 - 109 days ago Rating: 5 (3 votes) It is nearly impossible to figure out your conception date unless YOU personally know when it had to have been. Growing rates of baby's vary a lot as they grow bigger.. but in the beginning seem to develop at a very similar rate (this is why measurements of the embryo from early pregnancy are more accurate). As far as figuring out the conception date... if you don't know.. you probably won't know. Implantation can take up to 5 days... so even if you had sex one night, you may not have actually gotten "pregnant" (implantation) for up to 5 days.
