Question: can you see a pregnancy on ultrasound at 4 weeks?
Answer: Too Early in the Pregnancy The gestational sac is typically visible on a transvaginal ultrasound somewhere between 3 to 5 weeks of pregnancy, or by the time the hCG has reached 1500 to 2000. Before that, even in a viable pregnancy, there is not going to be a visible gestational sac on an ultrasound.
