Waiting for biopsy results

I had my biopsy almost 3 weeks ago, and was told I'd hear within 4 weeks. Is it a case of no news is goood news? If it was clear would I have heard by now? It was a gynaecology appointment, so was from my womb as far as I know, I never actually asked if it was my cervix or womb, was too sore to think at the time. I just know the doc said he wants to make sure he gets a big enough sample for them to test?

Trying not to worry, but can't help it.....
