Welcome to HCM!
After reading your question form my clinical experience I can say that you should see a gynaecologist. Had I been treating you I would go for an ultrasound
pelvis and adnexa to see if there is nothing of concern.
you have not mentioned your age or if you are in any physical relationship with anyone but the presentation can be due to preganancy-- periods less that usual with abdominal pain
, and diarrhoea
However, one can pinpoint the diagnosis only after routine examination and investigations.
Hope you get well soon
Feel free to ask more questions
