at how many weeks pregnant can you see baby with transvaginal ultrasound
The embryoâs heart begins to beat around 6 weeks of pregnancy â sometimes earlier, sometimes later. A transvaginal ultrasound (an internal ultrasound) can detect a heartbeat around 6 weeks of pregnancy. However, it isnât uncommon to be unable to detect a heartbeat via ultrasound until closer to 7 or 8 weeks. Find out more about week 6 of pregnancy in our informative pregnancy week by week series. Youâre More Likely To See A Heartbeat By 7-8 Weeks. Ultrasound machines can vary in technology. A motherâs size, the position of her uterus, the location of baby, and the accuracy of dating can all affect when a heartbeat is seen on an ultrasound. Even with all the variables, itâs very likely you will see a heartbeat by 7 weeks and extremely likely by 8 weeks of pregnancy.
