Waiting for endometrial biopsy results

Hi

I had a hysteroscopy and biopsy done 3 weeks ago due to post menopausal bleeding, which has now stopped. My hysteroscopy was clear no polyps or fibroids found. Just waiting for biopsy results. Has anyone had a clear hysteroscopy but still been diagnosed with cancer or a pre cancerous  condition. 

I feel so stressed out I'm in total limbo until I get these results.

Thanks
