Learn more about the development of the heart from weeks 5—10 below:. It may be possible to hear the heartbeat of an embryo from the fifth week of pregnancy. During an ultrasound between weeks 18 and 22 of pregnancy, a healthcare provider will check the fetal anatomy, including the heart. The heart rate of a fetus changes as it develops. In general, the rate is — beats per minute. A woman may have a scan to detect the fetal heartbeat at different stages of pregnancy. A doctor may recommend a scan as early as 7 weeks if the woman has had spotting, bleeding, or problems with a previous pregnancy.
A transvaginal scan is internal. The doctor inserts a device into the vagina to monitor the development of the embryo. However, until roughly the 7th week of pregnancy, the heartbeat of the embryo can be difficult to detect. A transvaginal scan can also be useful after 11 weeks if an abdominal scan does not provide a clear picture of the fetus.
During the second and third trimesters , a transabdominal scan can help assess the pregnancy. They then move a handheld ultrasound scanner device across the abdomen to find the uterus and fetus. By the second trimester, the heart of the fetus is fully formed, and the doctor should see the heart beating on the scan. URL of Article.

In , researchers at the University of Tucson in Arizona asked pregnant women to predict the sex of their baby. Seventy-five of these women claimed to have an intuition about it — as either a gut feeling or a dream — and of these women, 60 per cent guessed correctly. When women who had a preference for one sex over the other were removed from this sample, however, the 48 women that remained guessed correctly 71 per cent of the time.
Unfortunately, the study was never published, making it hard to scrutinise the details.
