HPV no abnormal cells for 2nd year in a row

Hi everyone,

 I'm new to this and just wanted some advice -

I'm 26 and last year I had my first smear test, the result came back with HPV and no abnormal cells.

Just had my second smear and the results have come back the same but they've invited me to come again for another smear next year.

From what I've read I thought they would have asked me to come for a colposcopy since it's come back with HPV for the second time on the run? 

Can anyone shed some light on this? Is this correct or should I get in touch with my GP? 

Thanks in advance x
