Suggest Treatment For Bleeding While On HCG Drops During Menopause

I am postmenopausal and did the hcg drops. While taking the drops I started to bleed and after a few days stopped the drops. Should the bleeding have stopped too? I continue to bleed. At first it was heavy, now it is less and at times I think I have stopped all together only to see blood the next time I wipe.---In other cases of postmenopausal women bleeding on hcg drops what have they done?
