Persistent symptoms

Hi I wondered if anyone has had a similar experience?

i had an abnormal first smear, suspected CIN3 which was later found to be a mixture of CIN3 and stage 1a1 cells, I had 2 LLETZ procedures and was then told that my second biopsy only showed inflammation and nothing else was necessary. Following this I had an ultrasound given to me as a reassurance and there was no concerns all normal. 

It has been over 3 months since my last treatment this and I’ve continued to experience infrequent vaginal bleeding, sometimes heavy accompanied by strong pains and at times unusual discharge and bleeding after sex.  

Ive booked back in to see the colposcopist but I feel a bit dramatic in doing so. Has anyone had similar experiences? Is this the norm?

Thanks
