When I was pregnant with my first baby in 1990, I decided against having a scan. Ultrasound during pregnancy and subsequent childhood non-right handedness: a meta-analysis. This was a rather unusual decision, as my partner and I are both doctors and had even done pregnancy scans ourselves- rather ineptly, but sometimes usefully- while training in GP/family physician obstetrics a few years earlier.
If you bleed after a vaginal scan, it will most likely be because there was already blood pooled higher in the vagina and the probe dislodged it.
One of the most important ultrasound scans you will have in the second trimester is an anomaly scan, which takes a close look at your baby and your uterus (womb).
Most women are offered a detailed scan at about 20 weeks to look for any structural problems or birth defects in the baby.
It may also be offered after 11 or 12 weeks if a trans-abdominal scan doesn’t give a clear enough picture.
From 11 or 12 weeks, including at the routine booking-in scan, it is more common to have a trans-abdominal scan.
