Every pregnant woman wants to know her due date.

During an ultrasound, a technician spreads a warm gel over the lower part of the abdomen, and then presses a tool called a transducer against the belly to examine the fetus using sound waves. An image of the fetus appears on an accompanying computer screen.

In early pregnancy, especially before 11 weeks, it is usual to have a trans-vaginal internal scan , where a probe is placed in the vagina. This gives the clearest and most accurate picture in early pregnancy. The person doing the scan spreads a special gel on your lower abdomen below your belly button and above the line of pubic hair. He or she then moves the scanner over the gel, sometimes pressing down, until the uterus womb and pregnancy can be seen.
That may give some information about your pregnancy, but it is less clear than an internal scan and that could possibly delay diagnosis. There is no evidence that having a vaginal or an abdominal scan will cause a miscarriage or harm your baby. 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.
