12w6d ultrasound

Amy • I'm 28 and married. Trying to conceive for 8 years and have PCOS. My baby girl is due December 18th!
First one is 8w4d second one is 12w6d. I was hoping for a real ultrasound but he went with the vaginal again. Was hoping for a better ultrasound picture and to actually hear the heartbeat. I know there's a lot of ways to guess what your having... any guesses based on these?
