welcome to HCM.
Cervical Ectopy also known as cervical erosion is caused by extension of normal cervical canal inner lining, extending to the external surface which is normally much stronger than the delicate cervical canal lining.
This sometimes causes bleeding during intercourse. and could be a result of long term use of contraceptives.
This should not prevent conception, but may cause spotting and bleeding during pregnancy
. It would be better if you treat the condition before trying to conceive.
Treatments available are chemical cauterization
(as already mentioned earlier by someone else), cryotherapy
(freezing technique), diathermy (heat technique) or Laser surgery
to destroy these cells in abnormal location.
Wishing you all the best.
