Thanks for the query.
For your bowel symptoms, you have already had a thorough workup.
As for the irregular cycles, pain during sex and inter menstrual spotting - all these 3 symptoms fit into one condition called endometriosis
It is when small bits of uterine lining become active and grow outside the uterus
It could also explain your bowel symptoms, as sometimes, it occurs on the lining of the bowel also.
I would urge you to consult a gynecologist, and specifically ask about endometriosis.
It is not always visible on ultrasound
, and is more of a clinical diagnosis, and can be confirmed by laparoscopy
THe treatment depends on the patient's age, profile, history, severity of disease, fertility
