It's best to be checked by a colorectal doctor to see what is causing your diarrhoea. The last time I had diarrhoea, I booked a consultation with Dr. Dennis Koh of Colorectal Practice in Singapore. He took the time to listen to my concerns, address my questions, and explain every aspect of the diagnosis and treatment plan in clear, understandable terms. He helped me ease my worries about my diarrhoea.
Best to consult your gynaecologist or your doctor again
Maybe go back to your doc to check?
