HI,
I understand your concern.
One month long bleeding with clots is a condition to be cared for., to avoid anemia, weakness that follows this.
Apart from pregnancy which has been excluded by your doctor, few hormonal imbalance,
ovarian dysfunction PCOD, fibroid uterus, uterine polyps,
adenomyosis or IUD
implantation can cause such bleeding in your age
You need to get investigated - CBC, Hormonal assays,
endometrial biopsy, USG,
Hysteroscopy,Pap test--as per need to pin point the diagnosis,
Consult a gynecologist to co relate your physical findings with investigation report & come to exact diagnosis.The treatment there after advised will help you.
Till the time you see your doctor, take rest, light nourishing diet, Cap. CVP gynae 2 capsules three times a day after food.
Take care.
Thanks.
