Biopsy of vulva - what could this be?

Hi looking for advice 

I had a lletz after my smear came back abnormal, the results came back good last month and I was told I would need a repeat smear in 6 months 

since then my vulva has been very sore and bleeding, my GP sent me back to the hospital today and they have took a biopsy of my vulva

what could this be ? All I seem to do lately is wait for results of biopsy and tests but I am confused about what could be wrong with me
