Oh, I understand how excited you must be waiting for confirmation, dear! Honestly, from ultrasound photos it is really quite difficult for us mummies to tell with certainty, even the experienced sonographers sometimes need a few angles to confirm properly. I think the safest thing would be to ask your doctor or sonographer directly at your next visit, as they can give you the most accurate answer when they see baby live on screen. Wishing you all the best, hopefully can confirm soon!
