Hello, Thanks for posting your query. I have gone through it and understood your concern. Persistent bleeding after settling down with the contraception should call for further evaluation by an expert. You need a proper clinical examination, a sonogram of the pelvis preferably in the trans-vaginal route, blood counts, coagulation and liver profile and urinalysis. Pregnancy should be excluded. Local causes like erosions, polyps and infections should also be excluded. Weight disturbances, stress, infections and use of certain medications create hormone disturbances and can cause such bleeding. Hope you find this information useful. Wish you good health.
