Ok mamas I just had a 3/D..4/D ultrasound and it was absolutely amazing!!! I loved every minute of it! The only thing is, is that it was about an hour long ultrasound! And the wand that was being used started to heat up my skin. How safe is this? Could baby feel it and will it harm her? I didn't think the session would go for that long but it did to try and get a good position of her. Anyways do you think my baby girl will be ok?
