Ultrasound scans in pregnancy

Ultrasound scans in pregnancy may be routine or they may be offered because of pain or bleeding or because of problems in a previous pregnancy. 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. From 11 or 12 weeks, including at the routine booking-in scan, it is more common to have a trans-abdominal scan. The person doing the scan spreads a special gel on your lower abdomen below your belly button and above the line of pubic hair. They then move the scanner over the gel, sometimes pressing down, until the uterus womb and pregnancy can be seen. In the first 11 or 12 weeks, this 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.

How early can a healthy pregnancy be seen on ultrasound scan? The earliest an ultrasound scan can identify a healthy pregnancy inside the uterine cavity is 17 days after the egg was released from the ovary ovulation. This is approximately three days after a missed period. Pregnancy tests are more sensitive and they become positive a few days before the period is missed, so there is a window of about a week between the earliest positive urine pregnancy test and the earliest the pregnancy becomes visible on scan.

This is a scan done early in pregnancy before 12 weeks of gestation. It is only natural to be curious and concerned about pregnancy and early pregnancy scans can give you peace of mind. Normally it includes a scan across your lower abdomen with a full bladder trans abdominal scan and an internal scan transvaginal scan. The internal scan does not harm the embryo in anyway and is a standard practice to obtain adequate details of early pregnancy.
