Vaginal ultrasound

I know this sounds so crazy.

I am currently 6 weeks and have my first appointment scheduled on 11/1. (3rd child, 4th pregnancy)

I had a miscarriage in April of this year. I had a vaginal ultrasound done then. It was ALMOST painful, on the line of uncomfortable and pain. There was quite a bit of blood and was told that and cramping was normal. I went in a few weeks later and had been told the baby bad no heart beat.

Apart of me thinks the vaginal ultrasound caused it and the other part of me is like, obviously that’s not the case. They wouldn’t be doing them if that was the case.

I guess I just need someone to ease my mind or tell me my thought isn’t illogical. I am seriously considering just canceling and waiting until the 2nd trimester this time around.
