Dating scan no baby
Most pregnant women are referred for their first routine (or booking) ultrasound scan somewhere between 11 and 14 weeks of pregnancy.
The purpose of the scan is: Some women may be offered a nuchal scan between 11 and 14 weeks.
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.
In some cases, if there is no sign of a pregnancy in the uterus, you may be given a blood test and possibly asked to return two days later for a repeat test.
Many hospitals also offer a further anomaly scan at 20 weeks, making a more detailed check of the baby’s development.
The numbers may be even more positive for women without previous miscarriages.
So things could still go wrong and sadly sometimes do, but as long as there is a heartbeat, the risk of miscarriage decreases as the weeks go by.
In a normally developing pregnancy the hormone levels double about every 48 hours and if the pattern is different, this can help to identify what is happening to the pregnancy.
If there is no sign of a pregnancy in the uterus and you have symptoms that suggest ectopic pregnancy, you are more likely to have both a blood test and an investigation called a laparoscopy, which is done under general anaesthetic.
