Hi, Thanks for using HCM.
Brown stain could be due trauma during intercourse, which is common, not to worry.
Minimal amount of white discharge is normal, if you have more white discharge need to get examined for genital examination. Swab test helpful after consulting your doctor.
If spotting continues need to get examined for any hormonal
disturbances or cervical lesions. PAP smear
and endometrial study are helpful.
Hope this helps you.
