A vaginal ultrasound could also be done, based on how many weeks pregnant you are.
For those who are going to get an early ultrasound, you may wonder what happens at 8 week ultrasound and how your baby is developing at this stage.
A strong fetal heartbeat should be clear on the ultrasound, and the heart rate should reach between 140 and 170 beats per minute by the 9 week of gestation.
Those who do not have a strong heartbeat will need to have a follow-up ultrasound to confirm the diagnosis because the fetus may not be viable.
You might also be able to tell if you have multiple babies in there.
This means that it is no longer an embryo and can be called a fetus.
In this case, you will have two options: to miscarry naturally when the time comes, or to undergo a procedure called dilation and curettage, or D&C.
About half of women who go through this kind of early pregnancy loss opt to miscarry naturally, while the other half opt for the D&C.
Even when you can remember when your last menstrual period began, ultrasound can still be more accurate than relying on your last period date alone.
The American College of Obstetricians and Gynecologists state the following: “Ultrasound measurement of the embryo or fetus in the first trimester (up to and including 13 6/7 weeks gestation) is the most accurate method to establish or confirm gestational age” (Committee Opinion, No. Even though using your last period date (LMP) is a traditional dating method, the accuracy of this practice depends on a regular menstrual cycle of 28 days, with ovulation occurring on the 14th day of the cycle.
