I've been having cramp like pain right under by belly button. The cramp progresses in a line towards my vagina and feels like a terribly sharp pull. My periods have also been lasting a day or 2 since the past couple of months. I had spoken to my friends about visiting a gynaecologist, both of whom have visited one but they advised me against it saying that they were both told that they won't be evaluated before marriage. What should I do? What could it be? Are these clearly a symptom of a disease.
