If, based on your last period, you’re 6 weeks along but you ovulated a few days late, it’s possible that the scan was just too early.
Later in pregnancy, genetics takes over your baby’s growth, and your baby will be measured in terms of percentiles.
For this reason, the FDA and ACOG recommend that only healthcare providers utilise ultrasound technology, and only as medically necessary.
Ultrasounds use sound waves to produce a picture on a screen.
In a routine and healthy pregnancy, it isn’t uncommon to have only one or two ultrasounds for the duration of the pregnancy.
While some women opt out of all ultrasounds, many choose to have an anatomy scan midway through the pregnancy, and a few will have scans early in pregnancy, to check dating and viability. Whether you have early ultrasounds or not is often a personal preference, combined with your personal medical history.
For these reasons, each woman is likely to see or hear her baby’s heartbeat at different stages in her pregnancy. Some women will have early ultrasounds to confirm pregnancy, or to check the location of the pregnancy if there’s any concern (e.g. Some scans can detect a gestational sac around 4-5 weeks of pregnancy, but that’s still too early to detect a heartbeat.
Your pregnancy is dated from the first day of your last menstrual cycle.
A transvaginal ultrasound (an internal ultrasound) can detect a heartbeat around 6 weeks of pregnancy.A positive test lets you know you’re pregnant, but seeing or hearing baby’s heartbeat often means the reality of your pregnancy will begin to sink in.Every pregnancy is, of course, unique in its development, and each woman’s prenatal care will vary.So your baby may be on the 30th percentile or the 80th percentile, but still be normal.Unfortunately, if you’re around 8 weeks of pregnancy, and your dating is accurate, a lack of heartbeat usually indicates a miscarriage.

Early ultrasounds might be used routinely, or only when there are concerns.
