Waiting for refferal

Hi, as the tittle says I've been waiting over 2 weeks now for an appointment at the breast clinic. Few weeks ago I noticed blood stained in my bra went to gp who said she couldn't feel any lumps but will reffer me. Since then I've had lots more stains. The wait is making me anxious. I know due to covid everything is taking longer. Does anyone roughly know how long the wait is or shall I call the hospital? I don't know what to do.
