Hello and welcome to HCM,
Lower back pain,
constipation and brown mucus discharge in stools is suggestive of lower gastrointestinal (GI) tract abnormality like
inflammatory bowel disease (IBD).
I suggest you to
consult a gastroenterologist for clinical assessment and examination of lower GI tract.
Colonoscopy is indicated to look for any abnormality or change in lower GI tract.
Pain during ovulation and
menstruation is common, however, if the pain is extreme and unbearable, you may consult your gynecologist for pain killers to relief.
Vaginal discharge can occur due to infection, congestion of pelvic organs or during sexual stimulation.
If the discharge is associated with bad odor, there is suspicion of infection and you need to get the vaginal discharge examined for evidence of infection.
If there is no evidence of infection, congestion of pelvic organs is the other possibility.
I am of the opinion that these symptoms are due to some abnormality of genital tract and gastrointestinal tract organs.
Thus, I suggest you to first consult a gastroenterologist for clinical assessment.
Thanks and take care
Dr Shailja Puri
