Endometrial cells

Hi all,

I received a letter regarding my smear test saying that the result was normal however some endometrial cells (cells from within the womb) were present in the sample.  The letter asked me to book an apt with my doctor but I cant get an apt with her for another 2 weeks.

Can anyone explain what this means and what may be required as a follow up ?  I've never heard of this so am unsure as to what it means and I am starting to worry a little !

Many thanks,
