A member asked:
Have had 2 transvaginal ultrasounds. due date has changed twice. due date is now 5/1/16. lmp was 7/12/15. confused on conseption date??
A doctor has provided 1 answer
Due dates & sonogram: Sonograms are only an approximate estimate of due dates. Due dates are also approximate but become more accurate as the pregnancy progresses and more parameters(landmarks) can be utilized to make that determination. Since your dates have been changed twice, your conception date may be difficult to ascertain.
