Thank you for your query
It would have been really helpful if we would have known your age. Cause these symptoms can be caused by a variety of causes (inflammatory bowel disease
, gastritis or gastroenteritis
, bleeding disorders etc). You should consult a gynecologist and a surgeon. They may run a series of blood tests, ultrasound
of the abdomen, may be an endoscopy as well. In the meanwhile you can start taking some antacids at least. That should give some relief from the pain for the time being.
Hope that helps
God bless you
