Hello,
Welcome to ehealthforum
Your symptoms are suggestive of Dysfunctional uterine bleeding. A light and persistent vaginal bleeding like you are having along with periods is suggestive of a hormonal imbalance.
The other possible causes of such disorder can be psychological stress, weight (obesity, anorexia, or a rapid change), exercise, endocrinopathy, neoplasm, drugs, or it may be otherwise idiopathic.
Laboratory assessment of hemoglobin, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, T4, thyroid stimulating hormone (TSH), pregnancy (by βhCG), and androgen profile can be done.Kindly visit a Gynaecologist for evaluation.Usually oral pills are prescribed for such conditions.
Take care!
