What is too early for ultrasound?

When Is The First Ultrasound Done In Pregnancy Understanding why ultrasounds are ordered during pregnancy can help parents prepare for the proper information. The excitement newly pregnant women have to see how their baby is doing via an ultrasound can send them to an Ob/Gyn quickly. However, it’s important that they’re patient when their doctor recommends waiting until they are six weeks pregnant for their first ultrasound.

  • Here’s why.
  • The first step women usually take after learning they’re pregnant is visiting with an Ob/Gyn.
  • During this visit, an ultrasound is frequently done to confirm early pregnancy.
  • But an ultrasound doesn’t immediately show what women might expect.
  • It’s typically not until a woman is six weeks pregnant that any part of the fetus is visible, which allows the doctor to determine whether a pregnancy will be viable.

Because of this, it’s important that women understand what information their ultrasound can and cannot provide at certain times during their pregnancy. And they should be prepared to wait to learn more about their baby, if it’s too soon. When Is The First Ultrasound Done In Pregnancy
