If there are concerns, a follow up ultrasound in the next few weeks will be able to give you more information. And another ultrasound weeks into your pregnancy will be able to provide more detail. This is because the uterus is still very small and is located deep within the pelvis. A vaginal ultrasound will allow the sound waves to get closer to your uterus and produce a clearer image.
At 6 weeks, your baby should measure approximately mm long or be about the same size as a lentil. It will be very faint at this stage and depending on the ultrasound equipment being used, you and the sonographer may not be able to see it at all. If a heartbeat can be seen, this can be seen as a tiny, flickering pulse on the screen. Right now, your baby may look like a little tadpole.
Although it is still tiny, all of its important internal organs are developing. This development will be using a lot of your energy so make sure you rest.

By Kate Daley October 28, We asked the experts all you need to know about that six-week ultrasound or first ultrasound appointment.
Your doctor will usually wait until at least six weeks to perform the first ultrasound. Remember, pregnancy is calculated from the first day of your last menstrual period. Instead, you will have a transvaginal ultrasound, where they insert a tampon-length transducer ultrasound wand into the vagina to see the fetus.
At around seven to eight weeks , the sonographer can confirm the gestational age your due date , plus or minus three days. Your doctor will continue to use this date as a marker throughout your pregnancy, says Kinnear. The technician is looking at whether the embryo implants in the uterus.
If it implants outside of the uterus, this indicates an ectopic pregnancy, which happens when a fertilized egg implants in the fallopian tube or somewhere besides the uterus. Where the embryo implants is also important as it can be higher or lower in the uterus. At this early stage, the sonographer will be looking for a yolk sac, which is attached to the baby like a balloon to provide nourishment, explains Kinnear.
The sonographer may or may not be able to detect a heartbeat, depending on how far along you are, says Wilson. The earliest you can see a heartbeat is at five weeks and two days gestation, says Kinnear. A transvaginal ultrasound given at this time is likely to show images of an early developing embryo. At this point the ultrasound technician can see the location of the embryo in the uterus and if it is an the proper, healthy location.
These scans can help determine if there are signs of an ectopic pregnancy. The transvaginal ultrasound at weeks can also show signs of the fetal heartbeat! At this point you will likely know if you have a twin pregnancy. It is around the 8th week of pregnancy that ultrasound photos will begin to have increased detail. The heartbeat is clearly accessible, as well as arm and leg buds on the growing fetus.
Although the earlier scans are possible and typically done by transvaginal ultrasound , the most typical first trimester ultrasound is recommended around weeks of gestation.
