Hello Dear
Please be calm
See 3 months is a large time for ulcer to heal.
If it is not healing then there must be some consistent irritation or some anamoly
I suggest you to get clinical examination or if possible video consultation to see if biopsy is needed or not
Next Steps
examination to see need of biopsy
etiology must be known
