Early pregnancy dating ultrasound
Before the advent of routine ultrasound in pregnancy, medical personnel estimated a baby's due date by the date of the last menstrual period and by feeling the uterus and determining the size to see if it matched the given due date.
With transvaginal ultrasound, checking for embryonic development known to occur within a certain time frame more accurately dates a pregnancy.
In fact, when a woman who has very regular, "textbook" 28 day cycles presents for prenatal care, this often turns out to be the correct EDC more often than not.
The most common misconception we encounter almost daily, has to do with how accurate ultrasounds are in fixing the EDC at different stages of pregnancy.
I don't want to give birth to a premature baby in a birth center (thinking i'm 37wks when i'm really only 36wks) with no NICU in case of breathing trouble or other problems, but i also don't want to be pushed into an unnecessary induction if i go too long (them thinkiong i'm 42 wks but really only being 41wks) My understanding is that before 12 weeks they are supposed to be accurate to within a few days.
I know mine (at 8.5 weeks) was only one day off from my ovulation day.
I was wondering if anyone has had a dating ultrasound and what your experience was - will they point things out for you? I'm Nervous to sit there and think the worst and not have someone able to answer my questions! Thanks :) I am having a dating ultrasound done next week (my guess is between 6w5d and 7w5d). Not to upset you but at 6-7 weeks there really isn't much to have pointed out!
I am In toronto and I know that the technicians can't really tell you anything. I got mine done, got a picture, and it was honestly a dot inside a uterus! If they give you a picture (you probably will have to ask when youre that early) then that means everything is most likely fine thus far!
