Hello .. mid-cycle brownish discharge --- at age 36 years needs to be assessed. The following additional information would be helpful : a) last cycle was it a normal flow and not delayed ? b) Did this bleeding / discharge start after sexual contact ? c) are you on pills for contraception d) any medical disorder like thyroid disease/ diabetes So the diagnosis would revolve around a disturbed pregnancy state ( abortion/ectopic) the Cervical polyp usually gives rise to fresh bleeding and vaginal discharge. so a vaginal speculum examination is required ( must ). If it is found to be injured the cause is polyp, so it has to be removed. The scope of Colposcopy is directed towards the early diagnosis of Cancer cervix. So, iit has to be correlated with other risk factore for cancer cx and appropriate decision taken. May be a punch-biopsy can be considered in view of the procedural costs. If you are on harmonal contraception then this could as well be a haromnal cause which is common. So the plan should be to get a vaginal exam done get to a diagnosis and start appropriate treatment. The stomach pain and back pain is most probably due to a pelvic infection, which is common with Chronic pelvic disease, ( Chronic cervicitis ) Thank you JN
