Hello dear
understand your concern
I think main problem in your case is brown
vaginal discharge.
Following are the cause of unusual bleeding:
1.
Hormonal imbalance
2. Dysfunction of ovary: PCOS
3. Uterine fibroid
4. Adenomyosis
5.Rare: cancer of ovary, uterus, cervix
6. Thyroid problem, endometriosis
7. Stress
8. Excessive weight loss/gain
9. Pelvic inflammatory disease
So I think yous should
consult doctor.
Do the following test
1. Blood test: FSH, LH, Estrogen,
progesterone, HCG, Thyroid hormone, ESR, CBC, Blood clotting abnormality
2. Pelvic examination
3. PAP smear
4. USG
5. Hysteroscopy
Maintain proper hygiene before and after sex/urination
Use condoms and lubrication during sex
Hope this may help you
Wish you good health
Best regards
Dr. Sagar
