It is understandable that you may have concerns about undergoing another transvaginal scan due to your past experience. In most cases, a transabdominal ultrasound can be performed around 8-12 weeks of pregnancy to confirm the presence of a gestational sac, fetal heartbeat, and estimate the due date. However, it's important to consult with your healthcare provider who will consider your individual circumstances and advise you on the best timing for an abdominal scan. They may recommend waiting until closer to 12 weeks when the fetus is larger and easier to visualize through the abdomen. Remember to communicate your concerns with your healthcare provider so they can provide appropriate care and support throughout your pregnancy journey.
