Thanks for the query.
Your pain abdomen and increased frequency of stools can be due to irritable bowel syndrome
of two months may not be because of IBS.
So you once consult gynecologist and take tablets to control the bowel movements.
Then you can get evaluated to find out the cause for your amenorrhea.
You may need ultrasound
to rule out abnormalities like PCOD and hormonal
profile to rule out hormonal problems.
Then with your doctor's advice you can take tablets to induce withdrawal bleeding.
