About two weeks ago I started having sharp stabbing vaginal pain, after a few days of that pain the pain started feeling like what I can only describe as vaginal contractions. The pain only lasts about five to ten seconds, but it is the most intense and horrible pain I have ever felt in my life. And the pain comes in waves I have about ten pains per hour. I am 20 years old, a virgin and I have a regular period. Does anybody know what is causing this or does anyone have the same symptoms?
