Can anyone show me their ultrasounds at that day..or tell me about their experiences?

I had two ultrasounds already because I was bleeding so much but HCG went up. Had one when I was still 3w6d and one today at 4w6d. But obviously couldn't see anything at all. My HCG was 500 today but has been doubling nicely in a little less than 48hours over the last week. So we're estimating it to be at around 1200iu on Thursday. The doctor said we should be able to see something then.

How was your experience?
