Smelly discharge on and off :-/

Hi I’ve just had lletz for cin3 and I’ve been thinking back over the last 6 months and I have had smelly discharge on and off and stupidly never got it checked out. I probably had 4-5 episodes of this.

Now I’m starting to think this was a sympton of cervical changes? Does anyone know if cin causes a smelly discharge or whether smelly discharge is only a sign of cc? (Im

still awaiting lletz biopsy results)
