urine samples

So I'm 28 weeks almost 29 and the only urine test I have done was during the scan for Down syndrome, I am active duty so it's a military doctor and I know we do things a little differently seeing that I am only seen every 6 weeks. But does anyone else see cause for concern? I intend on asking next appt but just was wondering if this is what's normal since it's been 6 years since my last baby.
