But in this particular pregnancy, we later determined that these babies each had their own placenta. Fraternal vs identical depends on when that egg split! Ultrasound cannot determine this right now and sometimes not at all. Now, genetics tends to get a little complicated. Because of this, some docs will have you wait until Weeks 7 or 8 in order to provide you with the most reassurance possible. Six weeks is typically the earliest a heartbeat can be detected. Most importantly, earlier than 6 Weeks and ultrasound will likely not be able to see what you or your doctor wants. If your doc feels your dates are off, you may need to wait. To me, motherhood has been so worth it! Why 6 Weeks Be Too Early for Your First Ultrasound

Pretty funny, right? Yes, we are confined to our children from the moment we see the little plus sign on the stick. It’s also called EDC, Estimated Date of Confinement. If it doesn’t, your doc may change your due date or EDD (Estimated Date of Delivery). Also, the measurement of the embryo (CRL or Crown Rump Length) should coincide with your gestational age. Because of this, some docs will have you wait until Weeks 7 or 8 in order to provide you with the most. Most importantly, earlier than 6 Weeks and ultrasound will likely not be able to see what you or your doctor wants. These babies each have their own main sac as well as their own sac of amniotic fluid.Īt this age, we should see the embryo, a yolk sac, and a heartbeat. If your doc feels your dates are off, you may need to wait. This type of pregnancy is called dichorionic/diamniotic. This image represents a split screen so as not to confuse–you can see that each fetus, labeled “A” and “B” are each in their own sacs. We can also see their heartbeats very easily at this point, too! Steady, strong, and rhythmic…just what we want to see. Crazy, huh? So tiny yet we can see these embryos so easily with the magnification and high frequency of a transvaginal probe. At 6w5d gestation, you can see that each embryo = 8 mm each.
