Endometrial biopsy....still waiting

Hugs to all fellow cancer sufferers/survivors....

I've been waiting for my hysterscopy biopsy results for over 3 weeks.... I followed it up but they said its not back yet. 

I was on Tamoxifen for breast cancer and had some random bleeding... the scan found that my womb lining was thick. 

I'm very worried about the results .... x
