Ob appointment

So after ttc for almost 10 months now, I have an appointment with at the ob clinic tomorrow to see what's going on.

What kind of things should I ask them to check? A friend of mine told me to have an internal ultrasound done and to check the blood flow in my ovaries. Will an ultrasound check my tubes to see if they're blocked? I just have no idea what to ask or what they'll do for me.
