What to expect from ultrasound?

angel
I go in on Monday for an ultrasound to see if I am ovulating. This is the first time for my husband and I to actually see dr.s and work on trying. We never really did anything to prevent it but it has been 15 years and nothing so we decided to go the dr. Route. I had all my blood works,and everything came back normal. I did have a 2hr insulin resistance and it came back high so she put me on meds and told me to cut the crabs. I have to go in for ultrasound day 14 after my menstrual. And that's mon. Is there anything I need to be a wear of? Would they be able to detect if something else is wrong with this ultrasound?
