Post lletz smear

Hi everybody.
Am after some advice. I attended my check up smear tonight. I told the nurse occasionally I bleed after sex. She said she would ‘have a look’ as she did the screening.
I had my colposcopy in April so I am now 8 months after. She said said my cervix still looked raw and that’s why I bleed.
I’m just wondering if this is normal? Or anyone else’s advice? I thought the cervix would be healed. Any comments grately received! Thankyou. Lisa xx
