Delays in screening results?

I had blood tests for the screening tests at my 12 week appointment. I was told my results would take up to 2 weeks via the post if all normal (and a phone call within a few days of the test if abnormal). I haven’t had any communication and it was 2 weeks ago today at Wycombe Hospital. Has anyone else experienced a delay? I realise my results are probably fine as I haven’t had a phone call, but I’d like to see the results!
