Hi! Incomplete D and C could be the cause of persisting brownish discharge. Other causes of brownish discharge
are hypothyroidism, cervical dysplasia, cervical polyps, cervicitis, vaginitis, cervical and uterine cancer,
uterine fibroids, hormonal imbalance (you have high prolactin levels and this would need to be re-assed),
genital ulcers, STDs and stress. You can discuss these possibilities with your gynecologist as on net and
without examining it is difficult to give a confirmed opinion. Hope this helps. Take care!
