Has anyone NOT been offered a test for gestational diabetes?

This is my second baby. I had a lower weight and was more active with my first (born 14 months ago), yet I was offered a gestational diabetes test.

This time around I haven’t been offered one, and I’m wondering if this is normal?

I’m slightly concerned I’ve fallen through the cracks of the NHS during this very busy time. I haven’t actually had a physical appointment with a midwife yet! I’m nearly 26 weeks.
