Inadequate biopsies



I had my first smear age 25 in summer and results came back mild cell changes and hpv.

attended colposcopy at the end of September and the nurse said there was what looked like some cell changes so she took biopsies. 

Biopsy results have come back stating inadequate for accurate assessment on my letter. Phoned the clinic to ask about this and they’ve said that the simple only had ecto cells and these were normal but they need me back for 2nd biopsy to collect ecto cells to confirm as it wouldn’t be okay to recall for 2nd colposcopy in a years time. 


Is this normal or is it something to worry about? I hate waiting around to find out. The repeat colposcopy isn’t for a month and then results take 4-6 weeks from that date.
