At my 13 week 4 day Appointment...

So let me start off that I went to a new doctor other than the one I went to for my son. I tried to call to make an appointment but they were always so busy! So I go to this new doctor.. Let me remind you I waited way longer than I was seen. When he finally came in the room he came in with a student and the nurse that took my BP. I literally laid down the student did my ultrasound moved it around and the doctor said baby and mom are healthy see you in a month! That's it ?? Really?? Didn't ask me if I had questions.. Didn't give me any prints of the sonogram, didn't let me hear the heartbeat . NOTHING! But that's besides the point of this post.. Lol okay so this may sound silly but when I was watching the baby I seen the legs open and in between the legs it was a circle with a line down the middle?? Can it be a boy?? Lol again I know it's silly.. But if anyone may have an idea?? Just to know ..for fun thanksss. 😊 oh and FYI, as soon as I left I called the doctors office where I took my son  and made an appt for two weeks !
