I had an internal ultrasound done at around 8 weeks with my first. Looked like a tiny pea with a halo which is why I asked earlier. Like said it can be done to prove pregnancy, etc. I was having severe back pain which is why I had mine. I don't believe they're routine though.

They're usually only to confirm the pregnancy, and usually only done in high-risk pregnancies or if a miscarriage is suspect because they're cost prohibitive. Doesn't sound like either of these is the case, though.
