Mammogram and biopsy

Hi .

I recently underwent a routine mammogram. I am 43 and have one yearly due to being high risk. I was called back in for ultrasound where they decide to take two biopsies. I was told I'd get the result in a week. The phone call came and I was told I needed to wait until 2nd December to discuss the result with a doctor. Obviously I am anxious. Usually I have my mammogram and receive an all clear letter in the post and thats that ! 

Has anyone been through a similar process and it turned out to be nothing ? I'm worried because a doctor needs to call me with the result ? I've not had a biopsy before so don't know if this is routine or not ? 

I'm worried sick
