its your vagina your baby and your life. you want your husband there so dont move it go and joke around with the doctor saying something like "o its nice to see you here today"
He's only saying that because half the time, when you're that early, its really hard to see baby on an ultrasound.
I would wait a few weeks... 6-7 weeks is really early for a first appointment. Although it isn't unheard of, its just early.
Around 9 weeks is normal for a first appointment.
He's just keeping you from going to an appointment where not much can be justified.
Your doctor has no reason to be mad..get a new doctor..
