Well I had an ultrasound at 5.5 weeks and it wasn't able to pick up very well so I had to have a transvaginal. It should be able to see it but not very well. Drs recommend waiting until 6 weeks for ultrasound.
At this stage, yes the ultrasound can be off by 10 days. Mine was off by ten days the other way, that is I thought I was 18 weeks and the ultrasound said 16 and a half. I knew when I had conceived because my husband had been away on a trip.
Subtract fourteen weeks (7 days x 14) from the date of the ultrasound.
When they do an ultrasound, they measure the baby's head and that's how they determine how far along you are. So if your baby's head is smaller than average, then they would give you a farther due date; If it's bigger than average they would give you a closer due date. Please remember your due date is an estimated guess, not the actual date you will absolutely deliver It depends how much the difference is and at what stage you have the ultrasound. At six weeks ultrasounds are accurate to within 2-3 days, by 12 weeks they are accurate to within 4-5 days and by 20 weeks they are only accurate within 5-7 days.
That means it is the date conceived (or within 48 hours of). It is never right on, but within a week of. Go by what the ultrasound says. No, if your ultrasound says 17 weeks and 2 days that would be that date plus 2 extra weeks, that is around the time of your last period, unless you have irregular periods or conceived straight after a miscarriage or something. The length of pregnancy is always measured from your last period even by ultrasound.
If the heartbeat is not visible at 11 weeks on an ultrasound, that would be cause for concern. The fetal heart begins beating approx. 22 days after implantation into the uterine lining. An ultrasound done at 6 weeks will confirm a viable pregnancy and you would be able to see the heart beating.
LMP stands for last menstrual period. 24W3D means that you are 24 weeks and 3 days along, there fore you would have conceived approximately 24 weeks and 3 days before December 14. However, those dates can be off as much as 2-3 weeks.
The only complication that can present would be an allergic reaction to the gel used for the ultrasound, which is very unlikely.
I was told the same thing. Based on my lmp I am 6 weeks but I had an ultrasound done 2 days ago that said I was 4 weeks. I wonder if I am 4 weeks along because that is the time of conception since you dont get pregnant the day of your period. It is usually two weeks later when you ovulate. Let me know if you have heard anything
My doc recommends at least 6 weeks and 3 days and even so it's early...Would try at 7-8 weeks
99% probability it was between 10 weeks & 10 weeks and 4 days ago.
Somewhere around the end of March.
No 6 weeks is very early for a scan which is most likely why he would like to see you again in a weeks time.
