hi welcome to HCM
-hi i had gone through your query and understand your concerns. i would come up with two possibilities to fit your condition .these include
1.the first one include, OVER DOSAGE HORMONE;in such cases deccrease the dose may be sufficient to spontaneous cure.
2.second possibility is,PRE CANCEROUS CONDITION;thorough examination may needed foe confirmation like pap smear
sometimes there is an underlying causes like ANEMIA,HYPOTHYROIDISM
etc ,so kindly rule out with possible conditions.with blood test
for Hb and thyroid profile
I hope this is helpful for you, thank you
