Elevated glucose in urine at 34/36 weeks?

So i've had +1 glucose in my urine my past two appointments at the midwife.

They didnt seem overly worried and asked me if i wanted to have the GD test rather than saying i needed too which i thought was a little odd, then they basically gave me a leaflet on it and sent me on my way.

Anyways, i have the test friday, i guess im just freaking out a little as everything else has been/is still completely normal. Little one is only weighing 5lb 10oz and im measuring right on track.

Anyone else had elevated glucose near the end of pregnancy?
