I had a ER scan at 5 weeks preg and he did a abdominal one at first but then did a vaginal one to look at my olveries and to try and see the baby... Well the tech said he was having trouble finding my left olvery (whole scan took 15-20 min) and there were times he was moving it in and out in and out like 10-15 times in a row (reminded me of a dildo to begin with and him doing that freaked me out) please tell me if this was normal or not... I have had vaginal US with my last 2 kids and my doc did not do this... I would have said something while in there but just figured different techs might have different techniques, trying to give him the benefit of the doubt.
