Throughout the the rest of your pregnancy you may have a number of follow-up ultrasounds, known as a biophysical profile and progress ultrasound. The objective of these exams is to watch your baby’s growth and well-being. Your baby’s coronary heart rate, respiration, movements, muscle tone, and amniotic fluid might be assessed, in addition to fetal measurement. Sometimes infants grow greater or smaller than anticipated, so physicians might request ultrasounds to assist guarantee a wholesome pregnancy.

If your twins are fraternal — which means, two different eggs have been fertilized — there shall be a separate gestational sac for each baby.
What happens at the six-week ultrasound?
By 20 weeks, most pregnant individuals could have already had their first ultrasound, however in rare circumstances, the 20-week ultrasound, also known as the anatomy scan, is the first. “We take a look at about 35 components, together with the mind, heart, kidneys, limbs, face, [sex], and extra,” says Jane Chueh, M.D., director of prenatal diagnosis at Lucile Packard Children’s Hospital Stanford in Palo Alto, California.

About 20 % of patients have “low-lying placentas” in some unspecified time in the future, Dr. Benacerraf stated, however less than 1 percent find yourself that way at the end.
What will they be checking at the first ultrasound?
The authors made the purpose that more accurate courting will scale back the amount of pointless interventions for post-maturity and can enable clinicians to higher determine true prematurity. However, it also should be noted that the diagnosis of two of essentially the most vexing problems, fetal development restriction and macrosomia, also rely upon gestational age. Sometimes an ultrasound raises extra questions than it could answer.
