Is an ultrasound EDD accurate if your period does not last normally seven days?
the EDD is the estimated date of delivery, with both of my children the edd was not correct. my first was born a week after the edd which was the date of conception plus 40 weeks. my second was born 10 days prior to the edd but i also had 4 different edd.
Estimated Date of Delivery is just that, Estimated. A baby can be born from 3 weeks before up to 2 weeks after with no problems.
With my first, his scan EDD was 10 days later than my period EDD and he was born on the scan EDD.
Second time around (twins) the scan and period EDD were the same but I was induced 4 weeks before with pre-eclampsia.
The only EDD that is accurate from an ultrasound is one done in the first trimester. The earlier the ultrasound is performed, the better. We measure what is known as the crown-rump length (the measurement from the top of the head to the baby's backside), and this measurement is the most accurate in predicting an EDD. First trimester ultrasounds are typically accurate within a week of how far along a baby actually is. Second trimester ultrasounds are up to two weeks off; and third trimester ones are up to three weeks off. What we are measuring, though, is how far along the baby really is--not when the baby will be born. As someone else mentioned, a due date is only an estimate--and only 5% of women actually deliver on their due date.
Can your last menstrual period show twenty three weeks but your ultrasound show twenty seven weeks which is more accurate?
Not really. Babies grow at pretty precise rates and therefore conception is pretty easy to answer at this early in your pregnancy. You are more likely to have your dates mixed up or that you conceived at a different time than you thought. Yes the date could be off a bit but ultrasound dates are usually pretty clear and accurate on dating embryos. Its all down to the measurements taken of the embryo and last…
When the doctor counts you as 7 weeks, they are counting from your last period. I figured if the ultrasound says 7 weeks, that is from around sep. 7th, the 1st day of your last period. meaning between sep. 18th thru sep. 24th could have got you pregnant. Likely the 21st. However an ultrasound of 7 weeks on 25th October gives you a due date of 13th June not the 3rd. See the Related Link…
What could cause heavy period-like bleeding with heavy clots and stabbing stomach pains too soon to be my period?
Im sure im 5 weeks pregnant not 7 and i had 2 ultrasound they both show sac but no baby is it too early to see the first 1 was at 3 weeks and then at 5 but according to the doctor im 7 weeks?
If you are 7 weeks from your last period, you are seven weeks pregnant, 3 weeks pregnant is before you miss a period and you would not have a scan then. If you are seven weeks and there is no sign of a fetal pole it appears that the embryo may not have developed and you will miscarry soon, I am sorry.
What could be wrong if your period normally lasts five days and this month it has lasted seven days and shows no sign of stopping?
It is unlikely that you gained that amount of fat and/or muscle in that period. If we assume that the scale was accurate at both points in time, then the most likely reason is your body has significantly more water in it now than it did seven days ago. timing of meals and bathroom visits can also swing the scale a couple pounds.
Can you be pregnant if you are seven days late on your period and cramping bt no bleeding could you be pregnant?
Do you mean can a baby be hidden in an ultrasound? if so, read my answer: yep....my sister was pregnant with twins but did not find out until she was seven months pregnant. All along it was assumed that she was only expecting one baby, until a routine ultrasound check up was done during a prenatal appt and the Nurse (not Doctor) saw more than one baby. Imagine the shock? Doctor missed the 2nd baby…
Should you be worried if you are 7 weeks pregnant and the ultrasound showed no heartbeat and no fetus but they say you are pregnant?
If they say you are still pregnant then you probably are. Seven weeks into the pregnancy is nothing. You have to take into consideration that they are going by your last menstural period when you could not have been pregnant so in actuality they are adding on a few weeks. Don't worry about it and try not to be stressed because stress is horrible for your unborn fetus.
