In circumstances where both approaches are readily available, the greater detail provided by transvaginal scans usually outweighs other considerations, and is preferred.
The patient is scanned in the normal examination position (dorsal lithotomy) with her feet secure in stirrups and her perineum even with the end of the examination table.
Abdominal scanning is performed with a full maternal bladder, provides a wider field of view, and provides the greatest depth of view.
Vaginal scanning is best performed with the bladder empty, gives a much greater resolution with greater crispness of fine detail.
a couple more days and they will be able to see the heartbeating. I have an encouraging story: had my first ultrasound two weeks ago, thinking I was about 5 weeks and 4 days along (I had been charting faithfully, and was pretty sure about ovulation).
Well, I just got back from the doctor, and they found a fetus and saw a fluttering heart!
Turns out my first positive (it was SOOOOO faint) was at FIVE dpo. I'm going back in 2 weeks when he said the heartbeat should be visible. It is looking pretty common so try not to worry ---- I am doing the same. I too had an ultrasound where my uterus measured 6 weeks (I could be a day or two short) and there was a yok sac but no fetal pole yet. I don't think this is bad news - at least not yet, so be positive! She thinks that our math is wrong and I'm more like 5 weeks.
It can be measured from the cervix to the fundus, AP diameter, and width.I am measuring 6 weeks and four days (I had calculated 7 weeks and 4 days).So, it's entirely possible to be even a whole week off WITH CHARTING!Normal uterine volume is less than 100 cc (nulliparous patients) and less than 125 cc (multiparous patients).Identify (if present), the gestational sac, yolk sac, fetus (or fetuses), presence or absence of fetal movement and fetal heart beat.
