Hey Rose, I was the same, I figured there was no point in worrying until there was something to worry about. Most murmurs are what they call 'innoncent murmurs' and nothing to worry about.

I got in the next day because there was a cancellation, otherwise I would have had to wait quite a few weeks too.

I was really worried about having to go 'topless' for the ECG, but when I went in they just got me to take my top and bra off then they told me to put a gown on, but back the front, the opening is at the front so they can still get to where they need but you are also covered. I felt totally comfortable in that respect. I also had a female sonographer which was a relief! She actually said all of her patients that day had been prg ladies, so it's definately a common finding I'd say.
