using the toliet more often and at the end of a wee it hurts

Hi,
Welcome to ehealthforum,
Brown discharge, itching, pain/discomfort, altered smell of vaginal discharge, etc could suggest chances of infection. Brown discharge is also associated with pregnancy. If pregnancy is suspected, or if you do not get your periods, or if you get abnormal periods, you should consider visiting your doctor/gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately).
If pregnancy gets ruled out, consider visiting your doctor/gynecologist for a vaginal swab/smear test done to confirm/rule out infective causes. Get started on treatment as indicated by examination findings and investigation results. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid use of tight fitting clothes. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. If infective cause is detected, and if you are sexually active, get your partner also treated simultaneously, and avoid having intercourse while being on treatment to prevent chances of re-infection.
Take care.
