What would you like to do?
Answer They are accurate within 2 or 3 days. But this does not mean that you will have the baby on your due date. Babies can be born any time between 37 and 4…2 weeks. That is what midwives are taught anyway. With my first my ultrasound said I was due 10 days after my period date but my husband had been away on a trip form the day after conception! Second time around the ultrasound agreed completely, and showed twins. (now 16) ANSWER Your last known period date or the date of conception is a better predictor....as all babies are different & you may have an extrememly large or an extremely small baby for it's gestational age, and when compared against babies in the "norm" the due date could be way off.
If your LMP was Nov. 4 and 3 ultrasounds showed your due date as Aug. 11 and one said July 31 what are the chances you got pregnant the last week of September?
Answer It's not possible at all. If your last menstrual period was November 4, you would've conceived somewhere around November 18-21, if you generally have… normal periods and ovulate on time. The general rule of thumb to determine a rough due date is to subtract 3 months from your LMP and then to add 7 days. Since one due date is earlier, it is possible that you could've conceived around the third week of October and November 4 was implantation bleeding. That really is the earliest conception would have occurred. Answer Well even with the earliest duedate that they gave me the date conception still lays at nov 6th which maybe i was wrong and my last day of my period was the 4th who knows. Answer And also I had a day of spotting dec 5th and then it stopped and i took a test
You were told you conceived on one date by an ultrasound but your lmp tells a different story off by 7 days but than again your cycles are 24 days which is more accurate?
Answer Hello. I would go with the date the ultrasound gave you but ultrasound dates can be off by a few to 7 days. Answer Both of t…hem are right. You probably conceived somewhere between the two. Most women ovulate 14 days BEFORE the missed period, as you have a short cycle this would mean 10 days after your LMP which would account for 4 of the 7 days, and even early ultrasounds are only accurate to within 3 days. The exact date would only be important if there had been two different men, and even then you would need a paternity test as it would be impossible to tell with such close dates.
When I had an 8 week scan i got a due date of 6 Dec however I found a diary which confirmed my last cylce was 6th Feb this would give me a due date of 16th Nov on a 35 day cycle Is the scan accurate?
Answer A last period on 6th Feb with a 35 day cycle would give a due date of 20th November but this still gives a 16 day discrepancy at a very early stage when t…he scan should be accurate within 2/3 days. Put the date of your scan on the discussion section and I will try to help. englishangel
Ultrasound at 7w3d baby measured right on that date However ultrasound at 13w3d baby measured 10 days larger LMP only lasted 2 days and was super light What would be your explanation?
Answer A 7 week ultrasound would be more accurate than a 13 week one especially if it agreed with your lmp. 13 week babies have plenty of room to move aro…und and sometimes it is more difficult to measure accurately.
Answer I believe that my due date from my ultrasounds were 2weeks wrong. They say i were due March 9th, but i believe i were due Feb 22nd. I ended up having my b…ub on March 7th and she looked well cooked. I would say they could be wrong but probably no more then 2 weeks either way of the date they give you. You have 2 rememeber the date is only an estimate, if you know what day your last period was or when you last had sex, if your able to work out your own date i would say somewhere in between your date and the ultrasound would be the due date.
Two months or so off the pill and you are pregnant and you had two periods that were 10 days apart how do you figure the due date which lmp do you use?
You get an ultrasound and have them date the pregnancy that way.
At 34 weeks pregnant and they did your first ultrasound at 9 weeks but your not sure if your period date was right can they still tell you accurately when your due date is.?
Answer most of the time at that point the dr can tell how far along you are by your size and size of the baby, but they could be wrong it happens all the time. i…f they do another ultrasound it will be accurate. with my daughter i had implantation bleeding , i knew it was because it was early and very light and only lasted a day. but the dr set my due date with that counting as my last "normal " period. i knew she was wrong so i calculated it myself and i was right! i went into labor the day i had calculated my due date to be. sorry this is long i do have a point:) if you think the dr went by the wrong period time, keep his due date in mind, but also recalculate from when you think you got pregnant. maybe youll be lucky and your real due date will be earlier than you thought! good luck! hope this helps!
Your due date was July 21 2007 and you had your baby July 23 2007 you got your due date from your first ultrasound at 10 weeks How accurate was this ultrasound and when did you conceive?
Two days late is perfectly normal. A date by ultrasound is only an estimate.
How do you figure out the approx date of conception based on your due date your due date is sept 18th your pregnancy is not consistent with your lmp your ultrasound was consistent with your due date?
The closest thought I have would be to go back 40weeks, then forward 2 weeks. This thought is based apon the fact of your aprox due date and taking it back to to what would ha…ve been the first day of your last period and then the 2 weeks forward would be roughly your ovulation time frame. I think that would be the best estimate you could ask for. btu who really cares!! for an advanced algorithm take a look at www.redbabybook.com
Every ultrasound my due date changes but only a few days apart. I need to know exactly when I conceived because I was with more than one person and dont remember my lmp?
Due dates are only estimates... All you can do is count 38 weks back from the due date to get the best guess on when the baby was conceived.
If your girl friends lmp was dec 26 2007 and you when for a ultrasound found out she was 8 weeks along and gave a due date of Oct 20 2008 what would the conception date be she cheated Jan 11 2008?
from her lmp her due date should be Sep 30, meaning she should have conceived Jan 9, give or take 5 days. Her due date is 20 days off. meaning her lmp would be Jan 14. she sho…uld have conceived around January 29, give or take five days, if she due on the 20th. ultrasounds aren't always completely accurate though. if she is completely sure of her lmp there is a possibility that both of your sperms could have been inside her around that time. You need a DNA test. but from the ultrasounds due date if she didn't cheat after jan11 it's definitely urs... ;) Hmm tricky one. Working back from the due date doesn't result in a hard and fast conceived date as sperm can survive inside the human body for several days before firtalisation happens. However, December 26th through to January 11th is probably too long (sorry, didn't quite follow the dates). I would ask for a DNA test as it will answer the question once and for all. Or, don't ask for a DNA test and accept the mother & child whoever's it is... :( AnswerFrom the dates you gave above that would just be impossible. If she was to be 8wks on Dec. 26/07 she would be due sometime in June/08 which would make conception in and around Oct./07 sometime. If her due date given was Oct. 20/08 and she was to be 8wks at the time of your ultrasound then that would make her have a baby 12months later. Your dates don't match up at all if she is to be 8wks at this time. You had better check all your information correctly.
