No periods since LLETZ - 3 months now

My last natural period was in August. 

Biopsy in September. One week of bleed. Missed period.

LLETZ in October. One week of bleed. Three of discharge. Missed period. 

Its now towards the end of November and still no period. 

I haven't had sex in a year and the GUM clinic pregnancy test result came back (unsurprising) negative. 

Anybody else had this? 

Yup, I had this. I personally think it's the stress and shock to the system of lletz. I skipped 2 periods, but all back to normal now. If you are worried ask your GP x
